Could not find this bug,

To reproduce:

1 Enter Read Mode in any document (had it on numerous .pdfs)

2 Exit Read Mode, and try to search or find the scroll bar

3 Search bar trapped halfway into document/under UI, scroll bar gone (another though less annoying consequence is the lack of automatic reformatting of the page when opening the left navigation tab e.g. bookmarks)

4 Note: search function and scroll bar are present and functional when going back into Read Mode

The problem arises when trying to use these functions after EXITING Read Mode.

Environment:
-Lenovo Yoga 720 (13")
-Windows 10 Home (update settings untouched)
-Google Chrome, Notepad, Microsoft Word mainly in background
-.pdfs vary from well-optimized documents with only text, to bloated documents full of layers and images, experienced in all kinds

Expected result:
When leaving Read Mode, search function and scroll wheel appear as before entering Read Mode.
