We’ve had some discussion about this recently on our community.
One of our users has a laptop with a touchscreen, but the lid is shut; he is actually using a non-touch monitor attached in single monitor mode along with a mouse. When viewing the ‘share link’ text it appears not to be highlighted in Chrome, but does so in MS Edge.
It took us a while to work out what could be going on: we were all seeing different things. Eventually we found this thread and it began to make sense - some of us were using touchscreens! We’re still unsure why it would appear differently in both MS Edge and Chrome though.
The user in question suggested there be a ‘copy to clipboard’ type button alongside the link itself.
Sorry for dredging up an old topic, we thought it might be useful to share.
