Flash CC Eraser Faucet Bug. Mac Only? (video included)

Question

I've reported this bug, but haven't heard a reply since I submitted the screencast video they requested.
This happens in Flash CC on MacOS X (10.8, 10.9 tested)
The issue: When using the eraser faucet tool to delete overlapping lines, the line or contiguous group next to the target will sometimes vanish. The Undo command will only bring back the intentionally deleted lines, not the ones that vanisheded on their own.
As a result, I can only get back all the overlapping lines I intended to delete, not the drawn object I wanted to keep.
I know this bug dosen't happen in CS3 (after using this tool extensively for a week on an animation project)

I haven't seen this bug occur on Windows yet, but if people want to try and replicate the bug demonstrated in the attached video, the results might be informative.

Answer 1

Here is a sample file to recreate the bug.
Instructions:
•Open File in Flash Professional CC on MacOS X 10.8 or 10.9
•Use the Erase Faucet tool to delete all the RED lines
•If a BLACK line disappears, attempt to Undo the action
Observed Bug:
Black lines connected to the Deleted red lines may disappear accidentally. 
Black lines which disappear in this manner do not reappear when the Undo command is used, only the Red lines do.
I've triggered the bug twice. The first time the left eye disappeared, the second time two fingers on the right hand disappeared, but the eye did not.
I recommend trying to delete every red line from the image, and see if a black line vanishes as described. If the bug does not trigger, reload the saved file and try again.
