qutebrowser still uses enum.Enum() as function in some places:

scripts/dev/check_coverage.py
49:MsgType = enum.Enum('MsgType', 'insufficient_coverage, perfect_file')

tests/unit/api/test_cmdutils.py
272:    Enum = enum.Enum('Test', ['x', 'y'])

tests/unit/utils/test_utils.py
563:        e = enum.Enum('Foo', 'bar, baz')

tests/unit/commands/test_argparser.py
31:Enum = enum.Enum(

Steps to reproduce:

1. Go to Tools > Preferences > General
2. Under Home Page select Use Bookmark
3. Select This Folder to set a bookmark folder as Home Page

Actual:
Bookmark selection menu allows selection of folders.

Expected:
In this case, bookmark selection menu should not allows selection of folders; it doesn't make sense to have a bookmark folder as home
