[Bug]: anyQuote nested quotes edge case, only with `inner`

[tuurep]

Bug Description

When there are nested quotes, having the cursor on the first character of a nested quote and doing .anyQuote("inner"), the wrong quote gets matched (the outer nested quote).

This only concerns .anyQuote("inner"), with exact same cursor position and .anyQuote("outer"), it matches as expected (the inner nested quote).

The same happens when the cursor is on the opening quote of an inner nested quote, but I'm not 100% sure of the expected behavior in that case. .anyQuote("outer") from that position matches the inner nested quote however and it feels correct to me.

Reproduction & Sample Text

Before

"'foo' and ´bar´"

After diq

Expected

"'' and `bar`"
