The update button when you're editing a post sometimes disappears when the post window extends too far downwards.

OS: Windows 10
Hardware: Cintiq Companion 2
Browser: Google Chrome

Issue: When you edit a post and the pop-up comes up, when adding more text it causes the pop-up window to 'extend' to the point that the Submit/Update button (whatever button you need to press to apply the update essentially) disappears into the bottom of the page and there's no way to scroll down to click it (as the only scroll bar you can click only navigates the actual text box and not the pop up; and the only other scroll bar is behind the pop up, clicking that cancels the pop-up and loses your edit). 

Related issue but possibly not a bug: Any time I make posts or edits to posts, after hitting "submit" the loading doesn't seem to end until I hit Refresh. Thankfully refreshing doesn't lose the actual post but it's still annoying. It could just be due to an influx in traffic, though, and the server slowing as a result. Still, worth looking into.
