Temperature adjustment follow by change in preset mode

[baunan]

Describe the bug Changing/adjusting the temperature in my case on 'Away' mode/preset. After final temperature adjustement, the preset mode is immediately changed to 'Home', the temperature is then changed on this mode instead of the intended preset mode (Away).

To Reproduce I have a very simple setup on my thermostat with only Home and away preset mode. When changing the temperature, it takes a moment after the last adjustment until the value is recorded.

1. In 'Away' mode change the temperature to 12 degc. After the final adjustment change directly to 'Home'.
2. The value of 12 is then recorded on 'Home'. In my case I had 22.5degC and it was changed to 12 as I changed to Home before the temperatuer was recorded on 'Away'.

Expected behavior As I changed the temperature on a different preset mode, then I don't expect it to change temperature on a different preset mode. So 1. Don't allow preset mode to be changed before temperature is recorded. 2. If preset mode is changed, then record the temperature for that mode and not for the preset mode it was changed to. 3. If the preset mode is changed before temperature is recorded, then cancel the temperature change.
