when the block "when loudness" or "when timer > 10" is dragged to the workspace, the project running status will turn to be true

[QinJhonny]

Expected Behavior

the project running status will turn to be true only after the green flag is clicked just as what scratch2.0 does.

Actual Behavior

when the block "when loadness/when timer > 10" is dragged to the workspace, the project running status will turn to be true. You could see the green flag button is active. right now my project use only one button for toggling start and stop, so this bug really gets me into trouble

Steps to Reproduce

just drag the block "when loadness/when timer > 10" to the workspace

Operating System and Browser

mac chrome 70
