Usually on Discourse, after selecting text, a pop-up window appears with a row of buttons including “Quote” and “Copy Quote”.
Recently, it has been found that on some mobile browsers, when these buttons are clicked, they simply disappear without bringing up the reply window or writing to the clipboard. Through testing on a self-hosted Discourse instance and on Meta, the issue is consistent. Changing the UA to use desktop view to operate still does not make them work. Checking browser settings to confirm that ad blocking and other options have been disabled shows no effect.
Currently, one problematic sample browser has been identified and the following tests were performed on it:
