Smoked glass wall persists when older traces are removed

1. Set up a page with a polling action that executes a SQL statement.
2. Click on a trace result to pop-up the SQL statement over a smoked glass wall 
(which disables the page)
3. Wait for new polling actions to fire until your selection is knocked off the 
displayed list
4. Your SQL pop-up disappears, but the smoked glass wall persists and can't be 
dismissed without reloading the page.

To fix either cancel the glass wall when removing the old traces, or preferable 
keep old traces while they're expanded. 

I'm on the current NuGet version (1.9), issue observed in IE8, IE9 and Chrome.
