Used the control + mousewheel to resize text smaller. Result: Sidewise window missing vertical scroll bar, sidewise tabs extend past right side without text truncation, missing refresh and close [x] buttons on tabs even if sidewise window maximized
Unbeknownst to me I resized the text a couple sizes down in the sidewise window by using control + mousewheel. Result: tab text continues past the right edge of the screen, there are no more refresh or close [x] icons visible anywhere, and my sidewise window no longer had any vertical scrollbar even with 100's of tabs, even if I maximize the sidewise window.
Recovered by selecting sidewise window and resizing text back up.
