This doesn't happen consistently, but every once in a while, this feature would completely crash and I'd have to restart my editor. The steps are as follows:

• I open a folder, I start editing some code.
• I right click the tab name, and click Reveal in Sidebar.
• The whole File explorer is highlighted in blue, without my file actually getting highlighted.

I checked the dev tools, and here is the error that gets shown:

  ERR TreeError [FileExplorer] Data tree node not found: [object Object]: Error: TreeError [FileExplorer] Data tree node not found: [object Object]

I traced it down to this line:

Which indiates that tree items are refreshed/updated somehow, but the key used to look up this map is still referring to the old object? Should this map be indexed by something else? item id (string)?
