left padding of virtual text `below` is highlighted when `wrap` is disabled and `number` enabled

[bfrg]

Steps to reproduce

Run vim --clean test.vim -S test.vim, with

vim9script

colorscheme habamax
set number nowrap
prop_type_delete('test')
prop_type_add('test', {highlight: 'ErrorMsg'})
prop_add(2, 0, {
    type: 'test',
    text: 'The quick brown fox jumps over the lazy dog',
    text_align: 'below',
    text_padding_left: 4,
})

Result: The left padding of the virtual text is highlighted when wrap disabled and number enabled.

Expected behaviour

The left padding of virtual text below should not be highlighted when the virtual text is added below an empty line.

I've also noticed that the way the cursorline is highlighted depends on whether wrap is enabled. Is this intentional?

The cursorline is almost not visible in the above screenshots. Here the same screenshots with a different colorscheme:

Left: wrap enabled, right: wrap disabled

I have opened a separate issue for the cursorline drawing: #11647
