1156991 - [Music][RTL] Navigating tabs transitions screen left to right; inconsistent with Clock

Status: RESOLVED INVALID

(Firefox OS Graveyard :: Gaia::Music, defect)

Description:
When a user is in the music app in an RTL language (Arabic), transitioning tabs between the splash art tab (far left) and any playlist tab (albums/artists/songs) will gesture the screen left to right. This behavior is identical to how the app behaves in LTR. This seems unintended when compared to how the 'Clock' apps behavior changes when moving between LTR and RTL languages.
Navigating tabs between lefthand tabs to righthand tabs (Alarm -> Timer) in:
* an LTR language -> transitions screen from left to right
* a RTL language -> transitions screen from right to left

PreReq:
* RTL language (Arabic) set in Settings
Repro Steps:
1) Update a Flame to 20150421010201
2) Open the Music app
3) Observe 'Album Splash' tab UI (far left)
4) Tap tab to the right (Albums/Artists/Songs)
5) Observe screen transition
*) Repeat above in LTR language to observe identical behavior
*) Repeat both above in 'Clock' app to observe expected mirroring behavior (Alarm -> Timer)

Actual:
Screen gestures off screen to the left, introducing new screen from the right: identical to LTR language behavior

Expected:
Screen gestures off screen to the right, introducing new screen from the left: mirroring LTR language behavior

Comment 2

[Dominic Kuo [:dkuo]]

Clock app and Music app have different designs(eg. Clock has no back button), so the page transitions shouldn't be the same.

Spoke with Dyan offline. Since Clock app comparison is not valid here (ie no back button in Clock, see comment 2), let's close this bug as resolved invalid. 
If needed, let's follow-up on a separate bug about what should be improved in Music app rtl behavior.
