Given the below HTML, in Firefox prior to 2018-2019 I was able to mouseclick a single option within the <select> and then press Cmd-A to select all options within it. As of today, I am not able to do so in Nightly. It still works correctly in Safari and Chrome. ```<html><body><form method=POST action=#><select multiple size=3 name=a><option value=1>One<option value=2>Two<option value=3>Three</select></form></body></html>``` I do not know when in the past few months this began, but I encounter it on BMO's editsearch page frequently.
