Reproes only on MacOS!
Tested on Ventura 13.5.1
Steps to repro:
1) Start an empty HDRP project
2) Create new VFX Graph, open it
3) Press space bar, or right click -> Create Node
4) When the window is open, move cursor to arrow button and press it twice without moving the cursor
Actual results: window expands and collapses but visual elements inside don't update or rerender. Leaves stretched elements. Only fixed by moving a mouse cursor
Expected result: As on Windows. Expanding/collapsing is instant. No mouse input is required
