Bug 1529059 [wpt PR 15420] - [BlinkGenPropertyTrees] Initiailize double_sided of synthetic effect, a=testonly Automatic update from web-platform-tests [BlinkGenPropertyTrees] Initiailize double_sided of synthetic effect Previously synthetic effects always had double_sided==false, causing the layer disappear when the backface was facing forward.

// mDocWasToBeDestroyed - Gets set when "someone" tries to unload the document
//   while we were prparing to Print. This typically happens if a user starts
//   to print while a page is still loading. If they start printing and pause
//   at the print dialog and then the page comes in, we then abort printing
//   because the document is no longer stable.
