Nonetheless, I was unable to find any bug referencing this, nor anything on Google, Stack Overflow, or the Apple Dev Forums.  So I began looking for things that could explain the differences between WebKit and Blink after the err uh, trial separation.

The closest reference I could find was a Chromium bug: https://code.google.com/p/chromium/issues/detail?id=356734&can=1&q=google%20maps%20performance&colspec=ID%20Pri%20M%20Week%20ReleaseBlock%20Cr%20Status%20Owner%20Summary%20OS%20Modified

Which describes a process called "layer squashing."  Searching the WebKit bugs for layer squashing showed this bug marked as "won't fix": https://bugs.webkit.org/show_bug.cgi?id=109992 from the same authors of the layer squashing now part of Chrome / Blink.
