Region matrix not updating RENDER SELECTED REGIONS bug both Mac and Win

[ribbider]

When rendering certain regions, if the region matrix is already open by the time I open the render dialogue, clicking on the render matrix to select and deselect regions either doesn't affect the render or works after 2-3 clicks.

Both on M1 Mac and multiple Windows machines (both Win11 and Win10).
To recreate:
Have a project with a few regions
Have a region matrix open with a few of them selected under "master track"
Bring up the render dialogue
Choose "selected regions" render
Click on the previous unselected region, the render dialogue is supposed to update the number of regions to render but it doesn't.
