Steps to reproduce the problem:
1. Open DevTools to record network requests
2. Got to a page that makes a fairly large number of network requests, e.g. http://www.bloomberg.com/
3. Click on the first network request
4. Enter "asdfsdfs" in the network request search field, so all requests are fitlered out

What is the expected behavior?
There is no noticeable delay.

What went wrong?
DevTools becomes unresponsive for a bit.

Did this work before? N/A 

Chrome version: 50.0.2661.86  Channel: n/a
OS Version: OS X 10.11.2
Flash Version: Shockwave Flash 21.0 r0

I looked into this a while ago but thought it had been fixed.

Each request is removed from the UI individually. If the request that is being removed is currently selected the selection moves on to the next request (removeChild calls updateSelectionBeforeRemoval). That request is then rendered, and then it is also removed and the selection moves on.

As a result the details for each request below the selected one are rendered temporarily.
