Pasting is slow.

[JohnBentleyDpi]

Pasting any text into a markdown file causes a slowly spinning wait icon before the text is inserted into a file. Does not occur in non-markdown files. Does not occur when extension disabled.

I've disabled/reenabled all extensions to isolate the cause to this extension. Recently introduced behaviour (some weeks).

To be clear, have you narrowed it down to an extension or this extension? I've gotten multiple reports of slow extensions that turned out to be due to a different extension. If you could please confirm this doesn't happen with all extensions disabled and does happen with only this extension enabled, that would be a good start. If so, please confirm you are using the latest version of this extension and see #291 for good next steps to collect a CPU trace. Obviously, pasting text into a Markdown file doesn't usually cause the problem you are reporting and if it happens when pasting "hello world" into an empty Markdown file, then it isn't a syntax parsing issue.

I haven't heard about something like this from anyone else and people paste into Markdown documents many thousands of times a day, so my working assumption is that it has something to do with your configuration. Some other things to try your scenario on:

• Different Markdown documents
• Another computer
• Open https://vscode.dev/ and install the extension
• VS Code Insiders build
• Uninstall and reinstall the extension and/or VS Code

In particular, https://vscode.dev/ is interesting because it's easy and a completely different install.
