To repro clone: [https://github.cds.internal.unity3d.com/unity/unity/pull/34832] if it's not merged yet!

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
