Safari seems to have been getting more developer attention this last year. This is good but also has resulted in a number of bugs and regressions as they move fast. Same is happening on Chromium.
I likewise have been involved in a similar bizarre bug. We wrote up a very detailed report with a reduced test case but sadly it has not received much attention. https://bugs.webkit.org/show_bug.cgi?id=247020
