Description Laurent Goubet CLA 2022-11-24 03:07:29 EST 
The EMFCompareContentMergeViewer normally disables the "copyAll" actions from platform compare when it opens (createToolItems(...)), but that only works when a sub-class of this is opened first. If the very first difference in the SMV is a textual one, then the Text CMV will be shown automatically, and this will sport have the duplicate action handlers. See bug 580988 for more details.

We need to check for and disable the duplicates in the text CMV as well, possibly ensuring that the ones we disable are indeed from platform and not our own.

Just to confirm, that's exactly the case when I see the "Conflicting handlers" exception.
