I get similar (but not identical) behavior using Expand/Collapse All in the browser. It appears to ignore the Shift key. i.e. Cmd-period expands/collapses the current bullet, and Shift-Cmd-period also expands/collapses the current bullet.

Ctrl-Shift-Period does not expand/collapse all, even if added as a user-defined keystroke. It does expand/collapse any bullets which are partly expanded!

And it also does not work on Windows 10 desktop and Windows 10 with Firefox 68. Expand/Collapse All simply does not work reliably.
