Exception when using quotes inside bracketed f-string

[scauligi]

=> #[f["{0}"]f]
Traceback (most recent call last):
  File "stdin-75e2587a4a8f7962cbde4e5df3ca4c83fa031704", line 1
    #[f["{0}"]f]
         ^
hy.reader.exceptions.LexException: unterminated string literal (detected at line 1) (<string>, line 1)

Seems like an edge case in the reader, since #[f["a{0}"a]f] works fine, but removing either of the as (or swapping either a with its neighboring ") brings up the error again
