LabVIEW front panel of reentrant VI doesn't close (in edit mode)

[Yamaeda]

If a VI is non-closeable and you manage to switch to non-editing mode with ctrl+m it can't be closed. I think the general option "Treat read only as locked" has a similar effect.

Could these be related?

Here labview 2023.3.1f1. I opened a class vi (preallocated clone) press control M. Edited. Try to close. Frontpanel does not close with the X button on the right top.

Pressing Control M brings back to clone mode. Still no closing possible.

Seems to be time to hunt down this bug because it is in labview for ages. I have to restart labview to get rid of it.
