When I click the comments button on the right, the width of the document view is not automatically adjusted, and adjusts only after I resize the browser window.
Before clicking:
after
Thanks for reporting.
No updates on this behavior so far.
A related issue - when I collapse the left panel where comments/highlights show up, the fit of the page does not adjust when I change the width of the browser window. It keeps the margin on the left. The only way to re-adjust seems to be to invoke “fit to width” from the menu.
I realized that if I first explicitly toggle “Fit to width”, then subsequent behavior is as expected when I hide comments bar on the right, or left panel. This sufficient for me!
