1308082 - IPC fatal error talking to bot on app.wire.com

Status: RESOLVED DUPLICATE of bug 1288997

(Core :: DOM: Core & HTML, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

Steps to reproduce:
 * go to https://app.wire.com/ , make an account (maybe that was on wire.com rather than app.wire.com), and log into the account on app.wire.com
 * say when "Otto the Bot" greets you, say hello to it so it sends you more text (embedded video and image)
 * scroll down to see that video/mage

Crashes reliably on opt and debug builds.
