matrix-sdk-base: Panic in the `RoomMember::normalized_power_level()` method
In matrix-sdk-base before 0.14.1, calling the `RoomMember::normalized_power_level()` method can cause a panic if a room member has a power level of `Int::Min`. ### Patches The issue is fixed in matrix-sdk-base 0.14.1. ### Workarounds The affected method isn’t used internally, so avoiding calling `RoomMember::normalized_power_level()` prevents the panic.
