Quick search - text highlighting not disappearing in notebooks

[andreamah]

1. Create a notebook that has the following string: tex text and open it.
2. Use the quick text search to look for tex by entering % tex in the file quickpick. Let this load.
3. Add a t at the end of the string so that it says % text
4. Notice that the highlight for tex is still there despite how the current query is for text
