Describe the bug

Sometimes apply completeItem will delete the character after cursor.

Reproduce the bug

</html>

type with different speed <space> + cl and select class completeItem. Sometimes it will delete the character >. I have seen this issue with coc-angular, coc-html, coc-flutter extension. All this extension will return completeItem with insertTextFormat: 2 and with textEdit. I checkout the output channel it seems it will send two completionItem/resolve request for the same completeItem.

this log does not delete the character >
log1.log

this log delete the character >
