Summary

The zoom percentage dropdown in the Codex built-in browser has a rendering/display bug.

When using the built-in browser’s responsive/device preview toolbar, the zoom selector shows the current value, but after opening the dropdown, the list area contains blank rows. One option such as 75% may be visible, but other expected zoom percentage options are not displayed correctly.

Observed behavior

• Open a page in the Codex built-in browser.
• Use the responsive/device preview toolbar.
• Open the zoom percentage dropdown.
• The dropdown opens, but most of the option list appears blank.
• Only part of the menu content is visible, such as one percentage option.
• The missing options make it unclear what zoom levels are available or selectable.

Expected behavior

The zoom percentage dropdown should display all available zoom options clearly, such as common values like 50%, 63%, 75%, 100%, and other supported levels.

The dropdown should not show blank rows or an empty-looking menu.

Actual behavior

The zoom dropdown opens with a mostly blank white list area. The percentage options are not rendered correctly, making the selector difficult to use.

Why this matters

The built-in browser is used to inspect and test web UI layouts. The zoom percentage selector is important when adjusting responsive previews and checking layout behavior at different viewport sizes.

If the dropdown options do not render correctly, users cannot reliably control the preview zoom level from the built-in browser UI.

Request

Please fix the rendering of the built-in browser zoom percentage dropdown so that all available percentage options are visible and selectable.

This may be a menu rendering, theme, contrast, or popover layout issue in the built-in browser toolbar.
