Steps to reproduce:

enable WR
open the attached file. This will use 1-2GB RAM. No need to let it load completely. Let it load for some time till it uses 1-2GB ram.
Close the tab. open about:memory
Minimize memory


Actual results:

memory doesnt go down. About:memory shows 1.2GB memory use as heap-unclassified


Expected results:

not so
To be clear, this bug is not about the page taking large amount of RAM. The bug is about unclassified memory, and memory not being released
This is a regression.

Rough range thati found:   [2018-11-20, 2018-11-27]   and then I stopped as a few builds in between just crashed/blanked out.

memory report after closing the offending testcase, and minimizing the memory
I'll take a DMD report, but probably won't be able to do so until I get back from next week's all-hands.

regression points to bug 1509592 (WR PR #3344) .. but that seems a little bogus.
Attached file emoji_working.html (obsolete) —
this also reproduces, but will actually draw the emojis.
