Hi there, @Anas12091101; since there will not be another Palm release according to the Open edX release schedule, I'll close this PR in the name of BTR. You can open a backport PR to the Quince branch to include these changes in the next release if you haven't already or wait until Redwood. Thanks!

@mariajgrimaldi, this issue is only present in the Palm release. When TinyMCE was upgraded to version 5 in the Palm release #30335, thexblock-utils version was not updated to one that supports TinyMCE v5. Consequently, xblocks or plugins using xblock-utils for rendering a WYSIWYG editor in Palm are encountering this issue.

@Anas12091101: I understand. Now, I closed this issue because, according to the Open edX release schedule, there will not be another Palm release. So, I'll take this conversation to the BTR Slack channel to hear what other folks think.

@mariajgrimaldi any updates on this?

[mariajgrimaldi]

Here's the thread I opened: https://openedx.slack.com/archives/C049JQZFR5E/p1710851198308489. So, we won't have a new palm release but you folks could use palm.master in your deployments.

I'll try finding someone to review/merge this, thanks!

thanks

Hi @Anas12091101 and @mariajgrimaldi, I was doing some tests and it seems to me that this change works perfectly, also taking advantage of this improvement, we took the liberty to upload this change to the sandbox (palm version) so you can corroborate that it works perfectly if you want :)
