Misaligned Glyphs in Berkeley Mono

Steps to reproduce

1. Using set guifont=BerkeleyMono-Regular:h16 as your font font link (can probably be repro'd with the existing trial
2. See attached screenshot comparing Vim in Ghostty terminal renderer vs MacVim:
   
3. The rounded corner graphics appear broken in MacVim

Expected behaviour

Unclear if the issue is because of how fallback fonts apply or if these are embedded glyphs in the font that are being mis-rendered

Logs and stack traces

No response

Vim configuration where issue is reproducable

No response

Issue has been tested with given configuration

• by running MacVim.app from GUI macOS interface
• by running vim/gvim/etc installed by MacVim
• by running other versions of vim (e.g. /usr/bin/vim)

Issue has been tested with no configuration

• by running mvim --clean (or gvim, supplied by MacVim distribution)
• by running vim --clean (in terminal, supplied by MacVim distribution)
• by running vim --clean (in terminal, other suppliers, e.g. /usr/bin/vim)

Other conditions

• The both Homebrew packages "vim" and "macvim" are installed

在 MacVim.app 中使用 BerkeleyMono-Regular、字号 16 重现该问题，并将圆角字形与随附的 Ghostty 和 MacVim 屏幕截图进行比较。然后使用 mvim --clean 重复测试，并记录行为是否发生变化；完成的标准是确定渲染或回退字体的原因，并确认 macOS Sequoia 上字形的对齐已修正。
