Auto tag completion slows down.

[Electricz0]

Issue Type: Bug

With indent-rainbow enabled, tag completion in html files slows to a crawl and often fails when typing quickly.

Never heard of this from 3 million installations. How could I try to reproduce it?

[Electricz0]

I was working with a VERY large HTML file, over 1,300 lines when I noticed the issue. To test it, I copied the source from a webpage (over 3,000 lines) into vscode and tried typing in a tag. With the rainbow enabled, the automatic tag closing would lag noticeably and fail if I typed too fast. With the extension disabled, it would work fine. I'm not sure if this will help, but I thought I would mention the issue.

I don't find 1,300 lines large. I just loaded a 78k lines HTML file into the editor and I can work without problems.

When I copy and paste big blocks, I can see how indent-rainbow "slowly" updates the view but I can just type normally. I guess there may be some interaction between the plugins which results in the problem. I fear I can't do anything about it. I would suggest that you simply disable the plugin for HTML or don't use it at all.
