Research direction

Start by reproducing the provided selector example and compare the parsed result with the original \a escape sequence. Trace the selector parser entry point handling attribute values, then verify that the escape and following spaces are preserved correctly in the output.

Written by the indexing model from the issue text.

Description

Unfortunately this example fails at the moment. It turns into \a into a (removes only the \). It seems a different problem though.
