long option is disappeared in optgroup

[Naoya Yamashita]

Hi, I'm newbie; let me know if there is a more suitable place for this post.

I found long option is disappeared in optgroup.
This behavior is speced or intended?

Test file:
```html
<select>
  <optgroup label="optgroup1">
    <option>shortshortshort</option>
    <option>
      longlonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglong
    </option>
  </optgroup>
  <option>shortshortshort</option>
  <option>
    longlonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglonglong
  </option>
</select>
```

1. Open the file via Google chrome

2. Click option, disappeared 2nd long option in optgroup. 4th long option without optgroup, it is displayed as expected

Environment:

  OS: macOS Sonoma (14.5)

  browser: Google chrome Version 125.0.6422.176 (Official Build) (arm64)

Can you search crbug.com and file it as an issue there if you cannot find an existing issue?

Thank you.

Thanks, PhistucK!

I zapped crbug, I couldn't find the relevant issue, so I filed a new issue.
