Diagnostics reload on mouse click

[Superpat]

I've noticed that my /LSP/Diagnostics window reloads on every click in the same code window. It's kind of distracting and downright annoying when there's scrolling involved since you lose the scroll point. I'm guessing that the whole diagnostics window is replaced on every draw, but maybe it should be patched instead ?
