Creases are not folding in combination with large multi-column environment

[mowi12]

I have a relatively large file which I want to structure. To do this I use the multi-column plugin. At the end of my file, I still have some sections which I now want to automatically fold, so I want to this plugin.

Normally, in every other file, my creases are folding. But in this file, the creases are not folding.

For context:

• The creases are outside the multi-columns
• There are about 100 Checkboxes in two consecutive multi-column environments.
• Settings are: 'Always fold creases' and 'Start folded'
• OS: Ubuntu 22.04.4 LTS

I tried to reproduce this behaviour with smaller files, but only this file, which is pretty big and takes about 1 second to completely load, has this problem.

After restarting the application, it now seems to work ... :D
