    <thetext>Both the GTK and WPE post-commit MVT bots are unexpectedly failing 3 tests since 313145@main

I checked that locally on WPE.

1.
Checkout &amp; build WPE on 313145@main
Run.
    $ Tools/Scripts/run-mvt-tests --wpe --headless --release --suite hls-shaka-test
    [...]
   - 3 tests were unexpected failures:
        HLS_MP2TS_AVC_AAC__Playback
        HLS_MP2TS_AVC_AAC__Seek
        HLS_MP2TS_AVC_AAC_PLAYBACK_START_TIME__Performance

Full log: https://build.webkit.org/api/v2/logs/52211875/raw_inline

2. 
Checkout &amp; build WPE on the previous commit (313145@main)
Run the same test: no unexpected failures/timeouts anymore.


This is the issue on the bots:

 * WPE last good run:   https://build.webkit.org/#/builders/1553/builds/8039
 * WPE first bad run:     https://build.webkit.org/#/builders/1553/builds/8040
 * GTK last good run:    https://build.webkit.org/#/builders/1552/builds/6439
 * GTK first bad run:      https://build.webkit.org/#/builders/1552/builds/6440</thetext>
