6) Begin typing a string like "mmmmmmmmm" into the Spreadsheet View's search filter

Expected behavior:
The Spreadsheet View should filter items without becoming unresponsive, as it did in previous versions of Nuke Studio:

 
Actual behavior:
When a large number of Track Items have been selected on the Timeline, the Spreadsheet View can become unresponsive and lock up when a text is added to the search filter.
 
Workaround:
If the Track Items are selected from the Spreadsheet View instead of the Timeline, this problem does not seem to occur.
