HMI sets forwardSeekIndicator and backSeekIndicator parameters for multiple Apps during SetMediaClockTimer request

[VjKlepikov]

Description:
HMI sets forwardSeekIndicator and backSeekIndicator parameters for multiple Apps during SetMediaClockTimer request from App1

Precondition:
1. SDL and HMI are started
2. App1 and App2 with HMI type 'Media' are registered
3. App1 is activated
4. App1 sends SetMediaClockTimer RPC with:
"updateMode":"COUNTUP",
"startTime": { "hours":0, "minutes":15, "seconds":30 },
"backSeekIndicator": {"seekTime":30,"type":"TIME" },
"forwardSeekIndicator": { "seekTime":30,"type":"TIME"}
5. The seek indicators are "TIME" for App1
'SEEKLEFT' button with "ico_seek_left.png" image is observed on HMI
'SEEKRIGHT' button with "ico_seek_right.png" image is observed on HMI

Steps to reproduce:

1. Activate App2

Expected result:

1. App2 is activated successfully
2. By default the seek indicators are "TRACK":
   SEEKLEFT' button with "ico_prew.png" image is observed on HMI for App2
   'SEEKRIGHT' button with "Ico_next.png" image is observed on HMI for App2

Actual result:

1. App2 is activated successfully
2. The seek indicators are "TIME"
   'SEEKLEFT' button with "ico_seek_left.png" image is observed on HMI
   'SEEKRIGHT' button with "ico_seek_right.png" image is observed on HMI
   

Environment:
SDL: https://github.com/smartdevicelink/sdl_core/tree/develop (fed2ae4)
HMI: https://github.com/smartdevicelink/sdl_hmi/tree/develop (ad2dc80)
SPT: 20210305-Android (1076)

@jordynmackool, Please notice this issue is related to feature Media Skip Indicators that should be released in the 7.1 release.

[Ypostolov]

Luxoft is working on it.

@Ypostolov please note @jacobkeeler may have already started working on a fix for this reported bug. Please allow me a day to confirm before you continue working on a fix so efforts are not duplicated.

@Ypostolov I was able to investigate the issue for a while on Thursday, but I wasn't able to find the actual root cause as of yet. I should be able to take on another task if Luxoft is planning on looking into the fix. Some notes I have from my investigation:

1. The reproduction steps are rather specific. If you set streaming indicators for both apps, the HMI sets them correctly from that point on.
2. Looking in the debugging console, it looks like the model for app2 actually has forwardSeekIndicator and backSeekIndicator set to {"seekTime":30,"type":"TIME"} in the scenario given, same as app1. This leads me to believe that parts of the model for app1 and app2 are tied together initially (possibly because of some nuance in how javascript and/or ember-js stores data).
