I can reproduce this in 17.0.0.

A workaround: start the selection, then use Shift-Right (letterwise) or Ctrl-Shift-Right (word-wise) or even Shift-Down (lines) to continue highlighting words for a copy.

Unfortunately, another potential workaround (using the "Copy" mouse-over convenience button) is also hidden by the same responsive design. In wide/expanded mode, this is available:

This is still a problem in 20.0.9.

This is not related to this app but an issue with the appnavigation of server core. This happens with every settings section.

Tested with current master (Nextcloud 28), this happens with every settings section when selecting text.
