Better scrollable support in Blocks tab

Hi - apologies if this has been mentioned elsewhere. My searches found references to scrolling issues within apps being built rather than scrolling within the Blocks tab.

When I am writing code in the Blocks tab, I have found that if I click and drag the scrollbar, the screen does not refesh correctly. It is only when I release the mouse button that the blocks tab refreshes and shows blocks correctly. Until then it renders a blank view. I have seen this with Chrome for both Windows and Linux.

I’ve also noticed the scroll mouse-wheel doesn’t seem to work either.

If these issues can be fixed, this would really improve useability of editing large amounts of blocks. Thanks!
