🐛 Fix EndDatePicker selection range progress

[balajis-qb]

Close #5599

Description

As mentioned in the linked issue, one of my previous PRs #5503 is causing an issue in applying --in-selecting-range over the hovered days.

We by default pre-select a selected date on the other months also. As a result the same date on the other months will be programatically pre-selected (even-though we didn't hover or select) and we use the same state to know the date till we want to highlight. The same issue also exist for startDate picker also, when navigating to the previous months - as we pre-select the already selected dates for the other months. So, as a fix I undo my existing fix.
