Library: Reading list action buttions often unclickable necause because courser is in pane resize mode

[ghost]

Platform

• YACReader/YACLibrary 9.6.2
• Qt 5.13.2 on Linux, 64bit, ArchLinux
  • Also reproduced with Qt 5.14.0
• Desktop: KDE Plasma 5.17.4 on X11

Issue

In the library, the action buttons in the reading list pane's header (create list, create label, edit, delete) in the sidebar are often not clickable because the cursour turns into resize shape on mouseover in the entire header region. The pane can then be successfully resized but the underlying buttons can't be clicked:

This occurs every time on casual mouseover. However, depending on the "angle of attack" on the button area and a random combination of alt/ctrl/shift keys pressed, sometimes the cursor turns out normal (in arrow mode) and the buttons then can be clicked.

I suspect something about the mouse event handling in this area being a bit awry.

Expected behaviour

The cursor should remain in array mode when over the header bar button area.

Sorry for the late reply, this somehow slipped through. I can confirm this bug also occurs on my machine. Not sure why this is happening, but I'll try to look into it.
