Status update for anyone who might be watching this PR:

I know it looks like not much is happening here, but gears are turning behind the scenes. We're working on testing, and I'm sure there will be things to fix before we merge this, but I believe we're getting close. If anyone in the community wants to try this branch, please comment here if you find problems! Other than the zoom icons -- we know about that one 😆

Thank you!

If all goes as planned, I'd like to merge this sometime this summer, specifically before North American schools get going again for fall terms. If we get lucky and it's even earlier, that's cool too!

Some of our friends at Google haven't signed the CLA, but that's OK for now. We're working through some paperwork, but we're all friends, and I'm not worried about it. It's just slow; I apologize for that.

On scratch-gui's spork-test branch custom block inputs get cleared when editing the definition (gonfunko/scratch-blocks#228).

If you make the following script and then click the green flag, nothing happens:

Switching to another sprite and then back to the first fixes it. This seems to happen because the VM receives a var_delete event for the message1 broadcast when a broadcast block is dragged onto the workspace. I wasn't able to find the exact cause of this, but it's related to potential variables.

Another issue is that the isLocal property of variables gets reset to false when switching sprites, which causes Scratch to think variable names conflict when they don't. To reproduce:

1. Make a project with two sprites.
2. In the first sprite, make a variable for this sprite only named "a".
3. In the second sprite, make a variable for this sprite only named "b".
4. Switch to the first sprite and back to the second.
5. Rename "b" to "a".

An error message will appear saying that "a" already exists, even though it's in another sprite. This doesn't happen if step 4 is omitted.

There are also some UI bugs:

• Up & down arrows don't work in context menus and dropdowns.
• Scrolling in long dropdowns (for example the "switch costume" dropdown if the sprite has many costumes) doesn't work very well. I can use the scrollbar and mouse wheel, but when I move the mouse after scrolling, it scrolls to the bottom instead of staying where it was.
• The lines on the direction picker are white instead of black in high contrast mode, which makes them hard to see:
