real time code generation incorrect while dragging?

Problem statement

It can reproduce with the online demo at: https://developers.google.com/blockly/ While dragging a block from toolbox, the real time generation of code is incorrect.

Expected Behavior

N/A

Actual Behavior

Steps to Reproduce

1. open ‘https://developers.google.com/blockly/’
2. use the “Try Blockly”
3. switch “Language” to “Python” (also fail with other language in fact…).
4. drag “if do” block in “logic”
5. while dragging, the generated code is as below:

if False:
  pass

if False:
 pass

which is incorrect and confusing to user. 6. stop dragging and put the block in workspace, the generated code is as below:

if False:
  pass

which is correct.

What’s the best way to implement a quick fix for those using compressed blockly?

@BeksOmega good observation. I think that should work, though I will need to see tests to be certain.

Another option is to return the empty string from workspace to code if mid-drag, but I can’t imagine that being good for existing uses. (Admittedly, neither is generating bad code, so maybe it’s an acceptable solution if you can’t get yours to work.)
