DataTable: The initial value of expendedRow is not reflected and the value change is not detected.

[bdh92123]

Describe the bug

If the expandedRow props of a DataTable is specified as an initial value along with some data, it is not reflected.

• It seems to operate by watching expandedRows prop, and the immediate property appears to be false.

If only part of the data specified as expandedRows is modified externally, it will not be reflected.

• Due to the same problem as above, the deep property seems to be false when watching expandedRows. It seems problematic that the entire value must be replaced to be reflected.
