Which @angular/* package(s) are the source of the bug?

language-service

Is this a regression?

No

Description

Prettier will format an Angular template using a plural i18n message like this:

<pclass="text-sm font-medium text-green-800"i18n>  @let count = bundles.value().length;  {count, plural,    one {{{count}} Stored Bundle}    other {{{count}} Stored Bundles}  }</p>

This compiles and works great but the third curly in the{{{ sequence is highlighted in red in VSCode and the bracket matching is broken as well for expression. It doesn't get the entire file into a bad state (in my testing) but it's confusing. Especially since it can't (?) be fixed without disabling the automated formatting or arbitrarily changing the text in the UI.
