 Replying to [comment:30 mcs]:

 > Unfortunately, it does not fix #24943. In fact, that issue occurs in Tor
 Browser 8.x even if NoScript is completely disabled and even when all of
 our bundled add-ons are disabled. The problem does not occur in Firefox
 ESR 52.6.0. All of these things seem to point to a browser patch as the
 cause.

 Thanks. I've reopened #24943 and merged the fix to `tor-browser-build`'s
 `master` (commit 448a263c986e4b824c5b4b205268e97fed88eb0c).
