Date/Time parameter reverts to default value unprompted

[Anonymous]

Setup:

1. "FromDate" date/time parameter with no default value
2. "ToDate" date/time parameter with default value.

"ToDate" default value:

= DateTime.Today.AddDays((-1 * Cint(DateTime.Today.DayOfWeek)))

Prerequisite: Publish paginated report to PowerBi Service

Steps to reproduce:

1. Select a "FromDate" value from the date picker
2. Change the "ToDate" value to any date greater than "FromDate"
3. Change the "FromDate" value to any date less than "ToDate"
4. Observe "ToDate" value

Actual: "ToDate" parameter reverts back to default value

Expected: "ToDate" parameters is not changed
