Describe the bug

When using dcc.DateRangePicker with updatemode="bothdates" from the UI, selecting the start date waits for the end date selection. However, selecting the end date triggers linked callbacks.

Expected behavior

In this updatemode, selecting the end date should wait for selecting the start date.
