1761758 - Enable live language switching when switching between LTR and RTL

Status: NEW

(Core :: Internationalization, enhancement, P3)

Description

[Greg Tatum [:gregtatum]]

This is a follow-up to Bug 62174, as there are more UI issues with the switch when this happens, and they can be handled separately from the main feature. This feature is gated on the pref "intl.multilingual.liveReloadBidirectional".

To fully test this feature ensure the following prefs are set:

intl.multilingual.enabled: true
intl.multilingual.downloadEnabled: true
intl.multilingual.liveReload: true
intl.multilingual.liveReloadBidirectional: true
intl.multilingual.aboutWelcome.languageMismatchEnabled: true
extensions.getAddons.langpacks.url: https://mock-amo-language-tools.glitch.me/?app=firefox&type=language&appversion=%VERSION%

Then switch between a LTR to RTL language, like Hebrew or Arabic.
