Unsaved content is lost when XSS warning is displayed

Every time I get an XSS warning, whatever content I had writen before saving is lost. Can we get the warning (and a reference to which is the offending text) without reloading the page to the last saved position. The solution is to save all the time, but because Grav scrolls all the way back up when saved, it makes it impossible to work on any document longer than your screen.
