Unresponsive expand/collapse group button on Calc (the '+' button)

I’m trying to use Calc on Windows on a high-DPI display, with a 250% scaling setting, and I noticed the ‘+’ and ‘-’ icons on the outline bar are completely useless. I can collapse a group by double-clicking on it, but once it’s collapsed it becomes impossible to re-expand it because the ‘+’ button simply doesn’t work. I also noticed the ‘level’ numbers on the header are so compressed it’s also impossible to distinguish or use them. I only realized Calc had them by reading about it on other related topics on this forum!
Any advise?

I can’t seem to find a way to edit the original question, but I’ve reported the bug:

Also, further experimenting showed me the buttons actually work when clicked EXACTLY on their upper-left corner. It seems there’s a scaling bug nonetheless.
