Merchandizing is not handling product selection gracefully when some variants combinations are not added to HQ.

If a product master doesn't release all combinations of product dimensions as variants, on e-commerce there is a chance after selecting product dimensions, the other product dimensions will disappear and cause users not able to select all variants.

For example, create a new product that has 2 colors (Black and Brown) and 2 options for Style (Wide Size 9 and Regular Size 10)

The product contains 3 dimensions with values:

Color - Black and Brown

Style - Wide and Size - 9

Style - Regular and Size -10

The released product variants are:

Black Wide 9

Brown Wide 9

Black Regular 10

Brown Regular 10

On e-commerce, when you select 10 - Regular - Brown, the size 9 and style Wide disappear, so the user cannot select size 9 variants anymore when the color Brown is selected.

In addition, With the 10 - Regular selected, the only option for this color is Brown so you are unable to change the color to Black.

It is expected that you should be able to go back and select the other Dimension (for example Black) and then show the available style (Regular 10.
