I'm wondering why this all still works the same, since you're always adding +1 to the line, regardless of a source map existing or not.

you're already adding 1 above: https://github.com/sveltejs/svelte/pull/8362/files#r1135771594

I've reverted these changes since it seems like there's some other bug that was present previously. Perhaps something like Rich-Harris/magic-string#248 which was causing some of our other source map tests to assert unexpected behavior

column: 0,
char: 53

same for the p, the previous combination of line 1, col 1 and char 7 would require cramming 6 chars at col 0.
