Steps to reproduce

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

vim9script

colorscheme habamax

prop_type_add('test', {highlight: 'ModeMsg'})

prop_add(2, 0, {

    text:  '└─ Virtual text below the 2nd line',

    type: 'test',

    text_align: 'below',

    text_padding_left: 3

})

Now move the cursor to the 2nd line, press A and then <CR>. Result: The cursor jumps to the first column of the screen line containing the virtual-text. And the 3rd buffer line is drawn twice:

While in insert mode, press some keys. Result: Text is inserted above the line containing the virtual text, but should be below it.

Note: when we move the cursor to the 2nd line and press o in normal mode, the text will be correctly inserted below the virtual text.

Go back to normal mode and press u. Result: The inserted text is removed but the 3rd buffer line is drawn twice again:

Expected behaviour

Text should be added below the virtual text when <CR> is pressed in insert mode, just like when o is pressed in normal-mode.

I just noticed that the virtual text isn't displayed at all when list is enabled.

I just noticed that the virtual text isn't displayed at all when list is enabled. If list is enabled interactively on the command-line, the virtual text disappears.

If wrap is disabled, the virtual text appears again, i.e. :set list nowrap works fine, but :set list wrap doesn't. Though, in both cases the same issue occurs when <CR> pressed at the end of a text line containing virtual text below it.

I fixed the obvious problem, but I haven't tried if that also fixes all the other situations. Please create a new issue if you can still reproduce something.

:set list still hides the virtual text, and it is displayed again with :set nolist
