The activity move feature is broken on first load

[Benjamin-unige]

When you try move an activity using the four way arrow on the top left of an activity it dosen't work and the browser console throw this error: Uncaught TypeError: this._dimCache is null on firefox and TypeError: Cannot read properties of null (reading 'w') on chromium

If you let go of the element and try to drag it again it works. It looks like something isn't initialized correctly on the first drag after the page loads

Apparently this is related to that issue https://tracker.moodle.org/browse/MDL-78771
I'm guessing remuiformat is making use of the same bit of javascript

I have a similar issue on Moodle v 4.0+. I am able to drag the section, but not its children. Also when I attempt to drag the section from the 4 arrows, I get this in the console log:
Uncaught ReferenceError: posObjs is not defined at switchToSheet (pubhtml?gid=2082587018&widget=false&headers=false&chrome=false&range=A1:C9:62:11) at pubhtml?gid=2082587018&widget=false&headers=false&chrome=false&range=A1:C9:98:17923
