TYPO3 Core

When I edit a content element that uses the HTML RTE in Opera (Default browser), the following markup ends up inserted at the end of the text body in the HTML RTE:

<div style="font-size: 12px; color: rgb(0, 0, 0); padding-top: 4px; padding-right: 4px; padding-bottom: 4px; padding-left: 4px; background-color: rgb(255, 255, 255); font-family: &quot;Arial&quot;, &quot;Helvetica&quot;, sans-serif; line-height: 100%; opacity: 1; border-top-color: rgb(0, 0, 0); border-right-color: rgb(0, 0, 0); border-bottom-color: rgb(0, 0, 0); border-left-color: rgb(0, 0, 0); display: none; border-top-left-radius: 7px;

Pasted "as is", I didn't want to reformat it in case it made it harder to pin down.

I have tried FF and Chrome (Release HEAD revisions for both browsers) and this problem does not occur. I also noted that it happened to me a couple of times in the Typoscript editor too, but have had a much harder time replicating the problem, so cannot effectively report on it.

In the HTMLRTE for text and text w/image elements though, editing the CE is enough to trigger the insertion. It is NOT inserted on save, it is inserted when the CE is opened. This was verified by viewing the HTML source, deleting the spurious markup, then saving the record. The markup is not visible, but as soon as you click to edit the CE, it is inserted at the foot of the copy again.

Perhaps some JS trying to generate a control of some kind is failing to execute / operating on some dicky markup. As usual if you wish to discuss with me in realtime I am in #typo3 on IRC.

Cheers guys!
