Error message underlines incorrect position if the pattern includes "\t"

[cr0sh]

repro: https://pest.rs/?bin=1exjwj#editor
grammar:

inner = {"b" ~ "c"}
rule = {("ax" | "a\t") ~ inner}

input:
a xbc # ("a\txbc")
output message:

 --> 1:3
  |
1 | a	xbc
  |   ^---
  |
  = expected inner

(maybe) expected output:

 --> 1:3
  |
1 | a	xbc
  |  	^---
  |
  = expected inner

Edit: updated repro for clarity
Anyway, thanks for an amazing crate 😄
