Summary Web Inspector: expanding "Show All Nodes" button in the DOM tree is very slow

Created attachment 91239 [details] Repro page Consider the following scenario: - open the repro page; - open Inspector; - in the "Elements" panel, expand <body>, <table> and <tbody> nodes; - observe that only 500 <tr> nodes are shown, and the rest are hidden behind the "Show All Nodes" button; - on the repro page, invoke context menu on the bottom node (having "9999" value), and click "Inspect Element"; - it will require a lot of time for Inspector to reveal the node. In contrast, the following scenario works fast: - open the repro page; - don't open Inspector; - on the repro page, invoke context menu on the bottom node (having "9999" value), and click "Inspect Element"; - Inspector will open, but will not reveal the node (this is another bug, I believe); - invoke "Inspect Element" on the same node again -- it will be revealed in Inspector in a timely manner.

Migrating to new component. This is still a problem in the current Web Inspector. I'm guessing that it's thrashing layout for every node :(
