Hiding columns via layout hints in a group rendering bug

[mattrunyon]

Description

Reported by Kevin S. in the community slack. When creating column header groups and hiding the columns in a group with layout hints, the group header still appears over the group. This does not occur with groups hidden via the side panel.

Steps to reproduce

Use this Python code

from deephaven import new_table
from deephaven.column import string_col, int_col
from deephaven.plot import Colors

letters_and_numbers = new_table([
    string_col("A", ["A", "a"]),
    string_col("B", ["B", "b"]),
    string_col("C", ["C", "c"]),
    string_col("D", ["D", "d"]),
    string_col("E", ["E", "e"]),
    string_col("Y", ["Y", "y"]),
    int_col("Even", [2, 4]),
    int_col("Odd", [1, 3])
])

letters_and_numbers_grouped = letters_and_numbers.layout_hints(
    column_groups=[
        { 'name' : 'Letters', 'children': ['Vowels', 'Y', 'Consonants'], 'color': '#FCD65B' },
        { 'name' : 'Vowels', 'children': ['A', 'E'], 'color': Colors.CORNFLOWERBLUE.to_hex() },
        { 'name' : 'Consonants', 'children': ['B', 'C', 'D'], 'color': 'CORAL' },
        { 'name' : 'Numbers', 'children': ['Even', 'Odd'] }
    ],
    hide=['A', 'E']
)

Expected results

Table with the groups, but the Vowels group is hidden.

Actual results

Table with the groups, the columns in Vowels are hidden, but the Vowels header still appears which makes the group headers over the wrong columns.
