BE calculator period date pickers to remember date/time selected even when not saved

Your version:
Major 3.11.0 - Minor v3.11.12

Repro:
Select a custom date period for a particular trading pair in the BE calc. Then switch tabs to another pair. Then switch back to the previous tab.
This behavior also happens when i remain on the same tab and create/edit/delete and order. If i had selected a particular date, the calc resets it. It should not reset it.

Outcomes:
The previous tab's date picker goes back to the original default date it was on. Usually this is a date of a position when it was started. It is annoying to have to constantly reselect the date period I want to be viewing. Often i switch tabs to view and compare data to the previous tab. I shouldn't have to constantly reselect the date I want. The BE calc should remember the date i selected.
