As you navigate the selection, the row number in the Go to row panel should change.

Use cursorRow for the input value, since there can be more than one row selected.

from deephaven import empty_table
t = empty_table(1000).update("x=i")

2. In the table, open up the "Go to Row" view (sidebar menu -> Go To)
3. Click in the table to move selection

Expected Results:
3. Row number updates in the Go to row view

Actual Results:
3. Row number does not update
