Prevents Github Copilot from suggesting an HTML contents line by line

[antoinehugueney-prog]

Describe the bug

Installed multiple extensions at once in VS Studio.
This included Copilot with many variants, but mainly the GitHub Copilot basic set for file editing.

• installed at the same time 'Polyglot Notebooks'

Then:
create a blank HTML file
just type <
accept as a completion

EXPECTED: next line is suggested, namely

BROKEN: next line is NOT suggested
Instead, the bottom tabs are switched to "Polyglot Notebooks".

Hence the suspicion.
Upon removal of this extension, the expected next line worked again.

Please complete the following:

Which version of .NET Interactive are you using? (In a notebook, run the #!about magic command. ):
7.0.410 (I know that Polyglot Notebooks requires v9, but it was not suppose to break Github Copilot in any way as far as I understand).
