Form not reflecting instance changes (Personalized Orbeon 4.4CE in Chrome V60+), was ok before

Hello
I am having trouble with my site in Chrome V60+ with Orbeon 4.4.
This is a known problem for versions 4.4 and lower, I imagine it comes from the deprecation of something in Chrome V60+.

My main problem is that I cannot for the moment recompile or use a precompiled Orbeon CE version as there has been some personilization in it, several things I am working on in my architecture.

I hope(d) I could fi the issue I have by modifying the resource_packaged which are directly in my deployed site.

Here is a description of my problem :
I have several instances, with params in it stating if the form is in read mode, write mode, differents ids etc.

I tried using triggers with setvalues and getvalues and from my understanding, the setvalues are ok, but the form does not refresh to match any changed values of the underlying instance.
i.e. if I change ith as xforms:setvalue my param <root ui:mode-write='false>... to <root ui:mode-write='true'> my forms stay in read mode and does not reflect the change in instance.

this "only" in Chrome V60+ (works ok in FF and edge and Chrome V59 and lower).

more details :
I put the following in my form :

                        <xforms:trigger  appearance="minimal">
                            <xforms:label>Open the element</xforms:label>
                            <xforms:hint>Navigate to the chosen element. </xforms:hint>
                            <xforms:action ev:event="DOMActivate">
                            <!-- modify the node used as temporary buffer for javascript parameter. is writen to the input field -->
                             <xforms:setvalue  ref="instance('temp-instance')/temp-id" value="instance(foo-instance')/root/foo@id"/>
                            <!-- retrieve the parameter in the input field in the document. -->
                             <xxforms:script ev:event="DOMActivate">
                                     window.alert("found Value :"+ORBEON.xforms.Document.getValue("temp-id-input"));
                            </xxforms:script>
                            </xforms:action>
                        </xforms:trigger>


With this line present in my main form body

<xforms:input ref="instance('temp-instance')/temp-id" id="temp-id-input" style="display: none"/>


2 checks I added :
                <xforms:trigger>
            <xforms:label>Press for show target</xforms:label>
            <xforms:message level="modal" ev:event="DOMActivate" value="instance('temp-instance')/temp-id"/>
         </xforms:trigger>

--> returns the correct content that whas just set

                 <xforms:trigger>
            <xforms:label>Press for show target input for orbeon</xforms:label>
            <xxforms:script ev:event="DOMActivate">
                         window.alert("ORBEON.xforms.Document.getValue :"+ORBEON.xforms.Document.getValue("temp-id-input"));
            </xxforms:script>
         </xforms:trigger>
 
--> returns the correct content that was just set In FF and Chrome V59-
Returns "" in Chrome V60+
     
I am trying to implement the changes in AjaxServer.Js described in the

Use jQuery to get elements with prefix, fix https://github.com/orbeon/orbeon-forms/issues/1461

but it does not seem to be the correct solution.

I also tried to get http://blog.orbeon.com/2014/01/orbeon-forms-441-pe.html

but with same lack of success

Any idear what I could try to backport in the resourcepackaged orbeon code 4.4 ?
any refs to commits that may fix the issue ?

Do not hesitate to contact me for any additional information or if you may have a hint on how to fix this.
Or even if you think you can spent some time on the problem.

Best regards
Olivier
