Bug: Hammer texture browser "Texture Group" setting is not retained when closing and re-opening the texture browser

[Wheattttt]

Describe the bug

As stated in the title. The texture browser in Hammer has a "Texture Group" option that lets you select from a range of different texture groups. however, when closing the browser and re-opening it, this texture group setting is reset to default, no longer filtering the shown textures.

To Reproduce

1. Open Hammer
2. Open the texture browser
3. Change the "Texture Group" option at the bottom left
4. Close and reopen the texture browser
5. Observe that it has reverted

N/A

Expected Behavior

The selected texture group should be retained, as it makes working with a specific group of textures really hard, especially for projects that are mounting games with a large number of assets.
