The details

#3248

Proposed Changes

Reverts a change made by #2247 (it was just meant for efficiency).

Reason for Changes

It broke things, because onScroll_ was no longer getting called.

Test Coverage

Bounds resizing

1. Attempted to drag a block outside of the workspace bounds.
2. Observed how scrollbars resized to show the block.

Cleanup blocks

1. Moved blocks to high x-coordinates.
2. Cleaned up blocks.
3. Observed how blocks were still in view.

Tested on:

• Desktop Chrome

Documentation

N/A

Additional Information

We could also add a call to this.centerOnBlock(topBlocks[0]); at the end of workspace.cleanUp if you want @NeilFraser .
