Weird Text Selection Behavior After Clicking Footnote or Comment

I use Dark Mode. If I click on a footnote or comment in the Editor to show it in Inspector and then try to use keyboard shortcuts (like Control-Shift-Left) to select text (instead of using the mouse), the text will be selected with only a white dotted border instead of the usual blue highlight. I have to actually select text with the mouse for the keyboard shortcuts to appear normal again when used.
