Enabledness of drop down params in effects does not update when changed in PF_Cmd_USER_CHANGED_PARAM

New year, new resolutions: report more of the bugs I find while developing Premiere Pro plugins 🙂  Hope you guys appreciate it.

And to start: I don't know since when this happened, but if you:

• Create an After Effects style plugin for Premiere Pro, and
• Have a checkbox param and a dropdown param under a section param, and
• Handle PF_Cmd_USER_CHANGED_PARAM for the checkbox to make it toggle the enabledness of the dropdown param to match, then
• Toggling the checkbox in Premiere Pro 24's gui does toggle the enabledness state of the dropdown param's label (greyed out vs. not), but doesn't adjust the enabledness state of the dropdown itself.  The user is thus still able to change the dropdown when he shouldn't anymore.  But:
• When you then close and open the section, the enabledness state of the dropdown param does change.

I also briefly tested this with setting the enabledness of a float slider param, and that one still works.  Also tested it in Premiere 2019, and there the enablement toggling does work as advertized.

Please pick up this bug, this must be extremely confusing for our customers...
