[Bug] Toggle sticky button does not work

[jcznk]

Hi @tatsumoto-ren,
first thank you for the add-on! I really like it.

I noticed that when the add-on is active, clicking on the Toggle sticky icon to make a field sticky does not have any effect.
However, if sticky is already active, you can still click on the icon to unstickify the field.
The F9 shortcut also works as expected.

(I'm testing on Windows 10
Version ⁨23.12 (fc492a41)⁩
Python 3.9.15 Qt 6.6.1 PyQt 6.6.1)

As far as I know this behavior is also present in other versions, such as 23.10. I don't know if anything can be done on our side to change it yet.
