The top 5 of extensions blocking the extension host process has a newcomer and that's emmet. In 1.31.1 it was top 20, with 1.32.3 it 2nd with 26037 hangs over 5 seconds. I don't have a profile at hand and I also don't use emmet but looking at its implementation might explain it, esp since it doesn't do things in LSP-style but in-proc, e.g probably slowing everything down when a file is large/huge
