Thanks for the work you all have done tracking this down. I am experiencing an issue with identical symptoms. I understand the problem should be fixed with 4.15+, so I may be experiencing a different bug. If anyone could help me determine that conclusively or point me in a direction that might help me fix this one, I'd really appreciate it!
Below I have reproduced the issue in the same way as above, with the same workaround.
