Viewing error message seen by users

[PlymWS]

Sometimes if I look at Who's Online I see that some users are viewing an error message page. Is it possible to change the alt text for the warning triangle to include what error message the user is looking at ?

If you have permission to see detailed locations, then the alt-text for the Stop-sign wil already show the error the user is getting in most cases.

I have the correct permission set. The stop sign shows the relevant error message but the warning sign ( /!\ ) only shows "Viewing error message".

Is there a way to have the alt text of warnings displayed like it does with the stop sign ?
