Hi, we have a submission being fired continuously in a loop, by using xf:dispatch with a 10-second delay. ie. something like this:

<xf:dispatch name="timer" target="timergroup" ev:event="DOMActivate"/>

<xf:group id="timergroup">
    <xf:action ev:event="timer">
        <xf:send submission="some-submission-here"/>
        <xf:dispatch name="timer" target="timergroup" delay="10000"/>
    </xf:action>
</xf:group>

It seems to run fine at first, but after leaving the page open for a while we notice in our logs that the submission begins firing twice per each 10 second interval, and then eventually 3 times, and so on until it's firing so many times that it actually starts affecting performance. It seems to start doing this randomly, so it sometimes takes a while to reproduce.

We're wondering if anyone else has experienced this, or if it's something that's been fixed in the latest version (we're currently using Orbeon Forms 3.8.0.201005141856 CE)?
