ALEHover text not appearing in floating preview

[jsit]

Information

VIM version

NVIM v0.9.0

Operating System: macOS

What went wrong

g:ale_hover_to_floating_preview doesn't seem to be working for :ALEHover

From the help docs:

When using Neovim or Vim with popupwin, if g:ale_hover_to_floating_preview or g:ale_floating_preview is set to 1, the hover information will show in a floating window.

Reproducing the bug

My minimal vimrc:

set runtimepath+=$HOME/.vim/bundle/ale
let g:ale_hover_cursor = 1
let g:ale_hover_to_floating_preview = 1

1. Use the vimrc above
2. Open a TypeScript file
3. Move cursor over a variable
4. Notice the :ALEHover info shows in the echo line, not in the floating preview

I tried doing :ALEDisable | ALEEnable to reload the settings, but this doesn't help.

I'm also not sure why these settings aren't showing up in :ALEInfo?

It looks like the truncated_echo conditional on line 47 of autoload/ale/hover.vim is evaluating to true, preventing it from getting to the floating preview check:

https://github.com/dense-analysis/ale/blob/506d392f6a72a2a494f9575c087e2f518811a534/autoload/ale/hover.vim#L47-L54

If I comment out lines 47-50, it works as expected.

I don't know how to make this not true?
