setMetadata causing ANR across many devices

Version

Media3 pre-release (alpha, beta or RC not in this list)

More version details

2ca41b03a383b8f0e30c917e9221dbdbf0f31114 (somewhat close to 1.8.0-alpha1)

Devices that reproduce the issue

According to Play Console:
Pixel 6a running Android 16
Fairphone 4 running Android 13
Samsung a52sxq running Android 14
Redmi Note 10 (sunny) running Android 12

around 0.10% of all users are affected, but my app has a rather small install base of 4850 users, make of that what you will (but I want to avoid reaching the bad behaviour threshold)

Devices that do not reproduce the issue

any of the devices I have :)

Reproducible in the demo app?

I'm not sure

Reproduction steps

I'm not sure, I can't repro this locally. In the code I just call setMediaItems, nothing special.

Expected result

No ANR

Actual result

ANR 1: Pixel 6a running Android 16
