Pasting image into quick editor causes page reload

[AndyB]

Steps to reproduce:

Go to a thread that has several replies.
Paste an image into the Quick editor.

Notice how the page first reloads (jumps to the top of the page) then back to the bottom of the page to show the Quick editor. Before XenForo v2.2.15 this did not occur. Pasting an image into Quick editor never caused a page reload.
