Single-line comment in javascript file gets evaluated as vim regular expression.

[Remich]

Problem: When writing a single-line comment at the beginning of a line (e.g. // foobar) in a javascript file the following error message appears:

Error detected while processing TextChangedI Autocommands for "*":
E35: No previous regular expression

As far as I know the // can be used inside some vim commands to refer to the previous search term or the previous regular expression.
It looks to me like some string is not being properly escaped.
I already looked into the source code, but could not fix it. Because I don't know where exactly the issue occurs.

Disabling nvim-cmp resolves the issue.
