When right-clicking the default scrollbar appears and allows scrolling past the editor

[Kenny2github]

Expected Behavior

Right clicking should function normally

Actual Behavior

The default scrollbar appears, and if you hover the mouse outside of the blocks area and scroll down it actually lets you:

Steps to Reproduce

1. Drag a block into the blocks area (what is it called?)
2. Right click it
3. Hover your mouse over the Stage (or anywhere other than areas with custom scrolling)
4. Scroll down.
   The entire editor will move upwards and there will be a large white space

Operating System and Browser

Chrome 59.0 Windows NT 10.0 JavaScript V8 5.9

This is also an issue on Chrome 59.0.3071.115 on macOS, but it's less apparent because scrollbars are invisible until you actually start scrolling:

Also, any context menu causes this issue (e.g. right clicking on the scripting area background [the menu with "undo"]; right clicking on a block in the block palette; but not browser menus [the menus with "back", "forward", "save image as", "inspect", etc]).

Thanks for reporting @Kenny2github, since the root cause of this is tracked here scratchfoundation/scratch-blocks#1023, I'll close this like the other one, so that they can be automatically closed with a PR to scratch-blocks.

@paulkaplan no problem! I’ll track that instead then :)
