Two finger touchpad scrolling causes the text input field to become misaligned with the block being created. I have yet to test this with a wheeled mouse. I will report back later
Update: I have successfully reproduced the bug on an iMac. The issue appears to be due to small window/screens. The sweet spot to view the bug is when the screen is smaller than 1024x640px, and can be in either X or Y directions
Update 2: The bug also persists on Firefox and Safari
