Description

Setting window borders view.entries.name = "wildmenu" causes window border settings to be ignored using vim.opt.winborder instead. This is especially frustrating for cmdline completions, where any border you set on your global vim options will cover what you're typing.

Steps to reproduce

Load the above config, which sets vim.opt.winborder to "single" and start typing some : command. Then execute :set winborder=none and try again.
