HI, I have observed a bug which happens sometimes after generating pdf print using chromium pdf.
For example, if I create a sales order, then tried to print it. It is no problem, but back to the sales order and the scrolling height will be limited to the pdf height, so I cannot see the whole Sales Order module, and will require a full refresh of the web to restore the original height. This is very troublesome.
Before printing: please take a note of the scroll height
Printing:

Back to the sales order page: as you can see the scrolling is kept as the printing page's height, so I need to make a full page refresh to restore it.
