[Bug]: Table Column Background Color Picker Is Unusable.

What happened?

When selecting a table section with associated columns in Affine, the table column background color feature does not work as expected. The color picker popup opens, but selecting a color is not possible.

Additionally, there is excessive spacing between the background color menu and the suggested color dropdown. When moving the cursor from the menu toward the dropdown to select a color, the popup closes before the user can reach it.

Works if you choose a curve path & not working when you want to go vertically.(the background color "click" is not holding the menu though)

Steps to Reproduce

1. Open Affine and create or select a table.
2. Select a table section with associated columns.
3. Open the table column background color option.
4. Try to select a color from the color picker or suggested colors.
5. Move the cursor toward the suggested color dropdown.

Expected Behavior

• The color picker should allow users to select and apply a background color to the table columns.
• The suggested color dropdown should remain open while the cursor moves between the background color menu and the dropdown.
• The spacing between the menu and dropdown should allow smooth and reliable interaction.

Actual Behavior

• The table column background color picker does not allow color selection.
• The suggested color dropdown closes when moving the cursor toward it.
• Excessive spacing between the menu and dropdown makes the color selection interaction difficult.

Impact

This issue prevents users from reliably customizing table column backgrounds and creates a frustrating interaction when selecting suggested colors.
