Details

While using the latest m-c debug build, I'm getting tons of the following assertions [1] while visiting gmail.

STR:

* launch the latest m-c in debug mode
** used: fx52.0a1, buildId: 20160919150946, changeset: 
* login into gmail and you'll see the assertions in the terminal once gmail starts loading

Example:

frame: Block(div)(0) (0x17f19acb8) style: 0x17edf7e10 {}
[Child 21503] ###!!! ASSERTION: Wrong parent style context: 'Error', file /Users/kjozwiak/projects/m-c-containers/layout/base/RestyleManagerBase.cpp, line 301
Wrong parent style context:  style: 0x17ea97c90 {}
should be using:  style: 0x17edf7c50 {}

Apologies, I forgot to add the changeset above. Used the following build:
* fx52.0a1, buildId: 20160919150946, changeset: fd0564234eca
Priority: -- → P3
Closing as I can't reproduce this anymore. Went through the STR from comment#0 using the following builds in debug mode and couldn't reproduce:

* fx56.0a1, buildid: 20170719151630, changeset: 4b32e7ce740e
* fx55.0b11, buildid: 20170719160203, changeset: af63b036dc7f
* fx54.0.2, buildid: 20170719170332, changeset: 10c24595231d
