Adjusting the selection window sidebar

The sidebar in the selection window in OS 26 is too small. I can adjust it when it opens, but these changes don't stick for the next time I open it.


Does anyone know how I might adjust it so that the adjustments are permanent?


The window in the image below appears when I select where to save the document in Numbers.

Odd. When I change the width of a sidebar in a dialog box, it 'sticks'. Even across apps, for example I just modified the Open dialog box here in Safari to make the sidebar very wide:


Then when I launched the Numbers app, it remained that way:


Perhaps not so odd, as with Tahoe I've been seeing differences in basic system behaviors between experiences users, such as the way Contacts cards backgrounds appear for me and dialabrain. I suspect there many unclear dependencies in Tahoe.
