This is the behavior with the version of boot.html without "favicon.ico".

The changes have been uploaded to Github, including boot.html with "favicon.ico" 
in it (in the Test directory). With these changes, the icon file name passed to 
Set_Up is used (at least for me on Xubuntu 21.10/Firefox 99.0/GNAT 11.2.0). What 
is your platform/browswer/compiler version?

Show_Message_Box does this, which is why the precondition on 
Dialogs.Selected_Test only allow two or more buttons. You could also change the 
precondition to allow a length of one.

I haven't tried that. You might also try "<br>", but I suspect button text is a 
single line. I'll look into this at some point.

Yes, Text_Areas and Text_Boxes don't handle HTML attributes (or any other kind 
that I've found).

The feedback is useful.
