Once I open a document in the search function, the highlighting disappears the next time.

When I search for a word in the search function, I get a list of documents that contain that word.

In the first document I select, the search term is highlighted correctly,

In the second document, the highlighting is gone and I can't find the word.

Same thing happens when I search for the same word again. I can only see the highlighting in the first document I open.

Please fix this.
