Release Notes:
Updated how clicking on multi-buffer headers works to provide better
control and prevent unexpected navigation:

Clicking the header now collapses/expands the file section instead of
opening the file.
Opening files can be done by clicking the filename or the "Open file"
button on the right side of the header.
Existing shortcuts continue to work: use the left chevron to collapse or
your keyboard shortcut to jump to the file
