Description

item.abbr too wide completion window does not aligned correctly

Steps to reproduce

config as above and edit a cpp file with configed clangd lsp.

Expected behavior

we can set the width of abbr field and completion window like view.document.max_width.
completion window is correctly aligned

Actual behavior

item.abbr too wide completion window does not aligned correctly

Additional context

No response

[Song-Tianxiang]

The completion windows are not aligned correctly, is this expected behavior? Or is it just something wrong with my configuration?

[Shougo]

Hm...

The completion window seems to be starting at an incorrect position because it is too large, trying to display all the completion candidates. To prevent this, I think you need to set a maximum width for the completion window.

Thank you. It works for me.
