Is your CPU busy? You could open Activity Monitor to check.

@roblourens I created new html file and i found that this issue only occurs when html file is lengthy
but on fresh file its not happening .

I can repro this by putting everything in view-source:https://microsoft.github.io/language-server-protocol/specification in a single html file and typing in it.

@octref why this is not resolved yet when it will be resolved still not resolved in insiders as well

Verifier: Test that emmet works as expected in various embedded languages in HTML, such as css/js (suggestion in css, no suggestion in js).

Test in large documents, such as the source of https://microsoft.github.io/language-server-protocol/specification, emmet completion is reasonably fast (compare with stable).
