fix(Highlighter): fix highlighter clear not working correctly with filter

[9inpachi]

Description

The Highlighter.clear has a bug because of which the filter parameter is not applied. The issue is with the Highlighter.selection[highlightName] getting reset which causes the full selection to be cleared even though the consumer may only want to clear the passed filter.

This PR fixes that issue by removing only the items to be cleared from Highlighter.selection[highlightName] and not fully resetting it.
