(feat) linked editing for html

[jasonlyu123]

#726
linked editing for element and component tag. Needs editor.linkedEditing to work properly. Without the setting, It does highlight the linked editing ranges with Ctrl+Shift+F2. but it doesn't seem to enable linked editing.

This works unreliably and I can't find out why. The result on our end seems correct. But it just stops working sometimes. And it will work again after restarting the language-server, In the same position. Need more research on the vscode side to see if there's anything we missed or it's a bug on their side.

Glad I'm not crazy and thought html tags inside svelte files should work with linked editing.

I haven't yet had an experience where linked editing does work but I've only been using VS Code with the linked editing enabled for about 20 minutes now.

I'll keep my findings posted here if my experience changes. Thanks for looking into this!.

I am guessing it's because the request takes too long. The problem usually happens when I switch files and immediately started linked editing. There is usually a lot of processing when opening the file so the request might take longer.
I can see a similar problem when setting the file association to HTML. But didn't see much complaining in the vscode repo. Maybe we can just add it and see the feedback.
