[5.x]: Matrix disclosureMenu error

[ZapaNOR]

What happened?

Description

When editing an entry every matrix block spawn a bunch of these errors:
Uncaught TypeError: Cannot read properties of undefined (reading 'on')
It seems this comes from the disclosure menu:
disclosureMenu.on('show', () => {...

Steps to reproduce

1. Create a matrix field
2. Set it to inline editable blocks
3. Add it to entry type
4. Create new entry, add a matrix block
5. Console gets around 8 of these errors per block

I've not tested this with a matrix field that is only 1 layer deep, but I get the error from the first layer.

Hi, thanks for getting in touch! I’m not able to reproduce this. If you turn on the safeMode, does the issue persist?

[ZapaNOR]

Yes, I get the same errors with safeMode(true) (confirmed all addons have been disabled by safemode).
Have you tried with matrix blocks containing matrix fields?

[i-just]

Thanks for confirming, @ZapaNOR!

Yes, I have tried various combinations of nested matrix fields before posting yesterday, but I missed the fact that the matrix field that contains the “Column” entry type has its label hidden - that seems to be the key to reproducing this.

I’ll update this issue once we have a solution.

Thanks again for reporting! I raised a PR for this.

Craft 5.9.6 is out with that fix.
