Description: I'm working on my dissertation and am using LibreOffice in combination with Zotero. I'm working with a 100 page document with lots of references added through Zotero (around 800). When having the navigator open in the sidebar and having the list of references expanded, there is a noticeable lag when typing anything in the document. The problem subsides as soon as the reference section is collapsed again. The problem also occurs when opening the same document in safe mode and after uninstalling the Zotero add-on, so that is not to blame here. Because the document is my dissertation, I cannot upload it here. Steps to Reproduce: 1. Open a large document with lots of references. 2. Open the navigator view in the sidebar and expand the references section. 3. Start typing somewhere in the document Actual Results: There is noticeable lag while typing Expected Results: Typing is instantaneous.
