Neovide hover popup overflows the window edge to the right/bottom and not staying within window boundaries

[juhaku]

Describe the bug
When hovered over method / function / struct etc declaration the hover box overflows over the right screen edge when opened with neovide. But when same operation is performed with neovim using terminal or in this case KDE's konsole the hover will not overflow the screen edge but stays withing the window boundaries.

I am aware there was previously bug related it overflowing to the left, but did not find a issue related it bleeding to the right of the window.

To Reproduce
Steps to reproduce the behavior:

1. Open any file which has language support protocol enabled with support for hovering documentation.
2. Either make window small enough (for example splitting) or make sure you have big enough hover documentation available.
3. Open hover e.g. hovering a function / method / struct / class etc. declaration.
4. See if the hover window stays withing the window (and within split window).

Expected behavior
The hover should stay within the window boundaries and not overflow to the right.

It also overflows to the bottom as seen in first image from neovide. The latter image is from terminal (KDE konsole) neovim.

This is probably fixed by #1786

@fredizzimo Just tested with master branch and result is still the same.

This looks like a Neovim bug, according to the logs it does not report the correct position. I will report the bug on their issue tracker. It might be possible that we are expected to do the positioning ourselves, but let's see what the response is first.

I think it's this code that is the problem
https://github.com/neovim/neovim/blob/996dd36c77321ea91758b5996d152a2f37af99dd/src/nvim/window.c#L986-L1018

This Neovim issue has been crated neovim/neovim#24801

[fredizzimo]

This will be fixed by #2029. But it would still have been better for Neovim to deal with it.
