7.90.009: after movie trailer viewtype is reset to wall

Running 7.90.009 with default estuary skin. Issue was present in previous builds as well.
If I go to movies (list view by default), select a movie, and click on "search trailers" I get an overview of trailers to pick (works fine)
However If I then go back (back on remote), the movie viewtype has switched to WALL.

Regardless if I actually watched a trailer, just having all the trailers shown is enough
I have a log but passwords for network shares are visible in it.

If it only occurs with Estuary then it is an Estuary-specific bug. You should report it here:
Bug reports

If it occurs with every skin then it is a general Kodi bug and can be reported here:
HOW-TO:Submit a bug report - Official Kodi Wiki

Thanks. already reported at estuary subforum. will try if it happens with another skin here as well.
