edge: select text in subgrid to copy

I have a strange problem. Client wants to copy the text of the link in a subgrid.

I have a custom entity. This custom entity hast 1:n relation to incidents. The incidents are shown on a subgrid on the form.

The first column is the title of the incident. This is also the clickable link to this incident. 

In Microsofts Browser Edge (and also Firefox, Chrome...) I am not able to copy the text (or a part of it) with the mouse. The non clickable cell (ticketnumber) can be copied.

This problem didn't exist with the old Internet Explorer.

Any Idea how I can get rid of this?

thx
