[MU4 Issue] Palette properties dialog - Problems clicking and scrolling

[poypoyan]

Describe the bug
While working on #11384, I found out that clicking the up and down button on "width" spinbox in Palette properties dialog seems to also 'activate' the "scale" spinbox! For all spinboxes, scrolling can only be done once per focus. This suggests a bug in focus.

This is likely to be P3, so I'll try to fix this.

To Reproduce
Steps to reproduce the behavior:

1. Go to Palettes.
2. Click on 'three dots'.
3. Click on 'Palette properties...'in the context menu.
4. Try to click 'up' and 'down' button on 'width' spinbox (single click and holding mouse button)
5. Also, try to click the textfield in the spinboxes, then scroll up or down.

Expected behavior
Spinboxes should work as expected.

I've assigned you @poypoyan for now and given it a P3 on your recommendation. Let us know how you get on trying to fix this!

Thanks!

@Tantacrul Hi! Apologies for this late reply. During around mid May-early June, I cannot work on all open-source projects I normally contribute.

Upon looking on this problem, I have no idea on how to fix this bug. This palette dialog is implemented in "PalettePropertiesDialog.qml" and uses so-called "Repeater" to generate the 4 "spinbox" options. This repeater looks alright to me. Apologies for this.
