Scheduler Edit Time Resets Days

[fastbike]

I've set a scheduler for Thursday to start at 9:00 pm (when my cheap power tariff starts).

I then edited it to try to add Friday as well, and change the start time to 9:30 pm (to avoid shock loading the grid with a heap of charger loads coming on at 9pm).
Bug: Changing the time resets the day checkboxes back to Thursday only.

Steps to reproduce:
1.Add a scheduler for Thursday (only) starting at 9pm. Save.

2. Edit the schedule. Change days to be Thursday/Friday without saving

3. Now change the time to be 9:30pm, watch how it reverts the days from Thursday/Friday back to Thursday only
   

This is a bug in the UI
