Dry runs of the upcoming central -> aurora merge result in crashes in Marionette:

https://treeherder.mozilla.org/#/jobs?repo=try&revision=e8cdb09267b6

Seth diagnosed this to be probably due to re-entrant manipulation of the CSSVariableImageTable (as releasing objects in that table cause other style contexts to be released and thus removed from the same table).
