Tabs bar / active tab position resets after printing
Open a sufficient number of files, plus about 3-4 more, so they don't all fit into the visible tab-bar, and the left and right arrows appear on the right of the tab-bar.
Click the right arrow on the tab-bar, as far as it will go.
Click e.g. the 3rd or 4th tab from the right, to view the file.
Click the print icon and print the file.
Note how the tab-bar has reset by placing the file you just printed as the rightmost visible tab, hiding the further-right tabs that were visible just before printing.
It's really irritating when you're printing a lot of tabs in order...
