Formatting incorrectly handles JS allman coding styles

[phosmium]

Describe the bug

When working with "svelte" extension, brace formatting is not allowing one to use allman style. It works just fine on "typescript" itself. It works on the upper if-clauses, but not if they're nested.

Reproduction

try to write nested if-clauses in allman style

Expected behaviour

It should indent just fine.

The svelte language server doesn't support on-type format, so it's definitely not formatting that caused the indent change. It's more likely to be an issue with VSCode itself. Besides, the same problem also exists in HTML files. It might be we need to tweak some TextMate indentation rules to make it work. But the TextMate language configuration is mostly regex-based, so it can be quite limited and not really possible to make everyone happy.

Supporting on-type format doesn't help either, Since we rely on Prettier for the formatting but Prettier doesn't have a configuration to format it this way. So I think we won't be able to fix it, at least not anytime soon.

This is also likely to be caused by the same problem as #1607

@jasonlyu123 -- yea seems like you're right. was able to workaround it for now with:

    "[svelte]": {
        "editor.autoIndent": "advanced"
    },

didn't notice any other issues yet since then.
