I am not sure I should be reporting this but buttons are overflowing the gray area on sales invoice form.I am assuming this is due to longish translation.
See screenshot.
I can reproduce this. It happens in English, too. The number of buttons has grown too large on some transaction forms for the allotted width, and their layout is not wrapping since addition of the previous/next buttons. Before, this was not an issue. It happens on quite a few different transaction forms.
I put this into bugs.
Fixed in the latest version (21.7.16)
