Syntax highlighting messes up when expressions contain }

void foo(String a) {
  print('${'test}test'}');
}

This would print the string test}test, but the } is messing up the syntax highlighting:

This is slightly better with LSP semantic tokens, but not entirely fixed:

The fix may be to remove any interpolated string expressions once Dart/Flutter stable channels fully support semantic tokens.

With d4d5fe8 , the interpolated expressions use the other parts of the grammar to parse so that strings are parsed correctly, rather than just looking for the next }.
