Delay for resizing the window

[xkmanlordx]

First of big fan.

One minor annoyance though: whilst using my tablet to take notes, when trying to press the save button, or open the sidebar, due to slight imprecision, the window resizes instead of clicking the symbol i was aiming for.
Maybe introducing a delay for the resize feature could help, although I can see how that could also be annoying, perhaps the hit-boxes could be made slightly larger, but I have no programming knowledge, so I'm just spitballing.

Either way, great app, many thanks for putting it out there.

Basically, events that are not handled by the buttons themselves are transferred to the titlebar, so some events can resize the window when clicking on buttons. I'm trying a PR to fix this (do not pass events to the titlebar)
