Reproduction steps

In a default exoplayer with a simple ImageOutput set, setting a playlist with multiple media items:
e.g.:
mediaItems.add(imageMediaItemBuilder1.setImageDurationMs(3000).build()) //[Image1]
mediaItems.add(imageMediaItemBuilder2.setImageDurationMs(3000).build()) //[Image2]
mediaItems.add(videoMediaItem) //[Video]
videoPlayer.setMediaItems(mediaItems)
videoPlayer.playWhenReady = true
videoPlayer.prepare()

Expected result

Image 1 is shown 3000 ms, Image 2 is shown 3000 ms, Video is played in its entirety.

Actual result

The image right before the video is shown just a few milliseconds, transitioning directly to the video. That is, Image1 is shown 3000 ms, Image2 is shown a few ms, Video is played in its entirety.

For some reason, it seems having a video next in the playlist "overrides" the current image.

When the media items are only images it works as expected (all images are shown the set ms) and with only video it works as expected
