title: How to fix disabled text highlighting?
body: <p>Text highlighting is not working for all input fields in my asp.net web app with the latest versions of FireFox and Google Chrome (CTRL+A does not work either). I have not been able to test older versions yet. With Edge it is working properly.</p>
  
  <p>Details: Double-clicking text or moving the mouse over the text while holding the left mouse button does not highlight the text. Surprisingly, dragging and copy/paste does work. So the text is actually selected but not highlighted.</p>
  
  <p>I searched through my CSS for <strong><em>disable-select</em></strong> but could not find a single occurrence.</p>
  
  <p>Any suggestions where else to look for a cause?</p>
