What is the issue with the HTML Standard?
One UX issue I noticed with customisable select: when the picker uses CSS Grid for a grid or multi-column layout, left/right arrow navigation does not behave as expected.
Because keyboard navigation still appears to follow a linear list model, navigation can feel broken or unintuitive when options are visually arranged in columns or spatial layouts.
It would be useful if customisable select supported spatial keyboard navigation that respected the rendered layout, or provided authors with a way to define directional keyboard behaviour.
