The PR was easy to do, I have just copied/pasted code from https://github.com/microsoft/vscode/blob/main/extensions/html-language-features/client/src/tagClosing.ts

The only thing that I noticed is that the tagComplete coming from language server should return only string instead of string+range.

I will create a PR on LemMinx side to fix that, but you can play with the PR now, it should work.

I decided to test this use case:

We could try to support adding the correct close tag by passing an array of cursors in the xml/closeTag request. Another way might be to make multiple requests to LemMinX (i.e. request close for first cursor, apply the result, request close for second cursor, apply...)

Then again, it might not be worthwhile to support this use case, since you expect the same text to appear at all the cursors when using multi cursor mode.

@datho7561 for the moment I would like to have the same behavior than HTML language feature. Your idea seems great, but perhaps we should discuss about that with vscode html language service team to have the same code tagClosing.ts

@datho7561 nice catch! However I think we can fix it later, as you said, the common use case, from a user standpoint, is to multi-close the same tags.

The code is just a copy/paste from html language feature of vscode.
