False positive flagging "there" to change to "their"

> While I was in there testing ...

`ThereToTheir` is surely seeing that the next word qualifies as a noun (gerund) but in this case it's probably more of a verb (present participle) but the key is likely to be that "in there" is already idiomatically a unit, which might be the way to early-exit the heuristic tests?

Start with the `ThereToTheir` heuristic and reproduce the report using “While I was in there testing ...”. Trace why “in there” is treated as a correction candidate, then verify that the idiom remains unchanged while genuine there/their cases are still flagged.
