For definitions not working on alternate config for select

[roni-estein]

Sorry the title is almost meaningless, I couldn't figure out a best way to describe it.
Issue: I have more than one default for custom form plug-in:
The code should clear it up, I'll post the whole webpack.mix.js at the end for reference, but for example this segment:

customForms: theme => ({
default: {
    'input, textarea, multiselect, select': {
        width: theme('width.full'),
        borderRadius: theme('borderRadius.none'),
        borderColor: theme('colors.gray.400'),
        borderWidth: theme('width.px'),
        fontSize: theme('fontSize.sm'),
        boxShadow: theme('boxShadow.md'),
        paddingTop: theme('padding.3'),
        paddingBottom: theme('padding.3'),
    },
    checkbox: {
        height: theme('height.5'),
        width: theme('width.5'),
        boxShadow: theme('boxShadow.md'),
        color: theme('colors.brand.600'),
    },
    radio: {
        boxShadow: theme('boxShadow.md'),
        height: theme('height.5'),
        width: theme('width.5'),
        color: theme('colors.brand.600'),
        icon: '<svg fill="#fff" viewBox="0 0 16 16" xmlns="http://www.w3.org/2000/svg"><circle cx="8" cy="8" r="4.5"/></svg>'
    },
    'input, textarea, multiselect, select, checkbox, radio': {
        '&:focus': {
            borderColor: theme('colors.brand.400'),
            boxShadow: theme('boxShadow.outline'),
            transition: 'box-shadow 100ms ease-in-out',

        },
    },

},
required: {
    'input, textarea, multiselect, select': {
        width: theme('width.full'),
        borderRadius: theme('borderRadius.none'),
        borderColor: theme('colors.gray.600'),
        borderWidth: theme('width.px'),
        fontSize: theme('fontSize.sm'),
        boxShadow: theme('boxShadow.md'),
        paddingTop: theme('padding.3'),
        paddingBottom: theme('padding.3'),
        paddingLeft: theme('padding.3'),

    },
    'input, textarea, multiselect, select, checkbox, radio': {
        '&:focus': {
            outline: 'none',
            borderColor: theme('colors.brand.400'),
            boxShadow: theme('boxShadow.outline'),
            transition: 'box-shadow 100ms ease-in-out',

        },
    },
},

Defines a default, in my case optional variation that seems to work perfectly.
creating form-input, form-select,form-checkbox etc....

It also creates the group: 'form-input-required, form-select-required` and so on

I've noticed that default form classes all work perfectly, however, the required form classes actually work, but not for "form-select" which is defined but missing issues.

Images:

Rendered CSS:

.form-select {
  background-image: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 24 24' fill='%23a0aec0'%3e%3cpath d='M15.3 9.3a1 1 0 0 1 1.4 1.4l-4 4a1 1 0 0 1-1.4 0l-4-4a1 1 0 0 1 1.4-1.4l3.3 3.29 3.3-3.3z'/%3e%3c/svg%3e");

  box-shadow: 0 4px 6px -1px rgba(0, 0, 0, 0.1), 0 2px 4px -1px rgba(0, 0, 0, 0.06);
}

.form-select-required {
  width: 100%;
  border-radius: 0;
  border-color: #718096;
  border-width: 1px;
  font-size: .75rem;
  box-shadow: 0 4px 6px -1px rgba(0, 0, 0, 0.1), 0 2px 4px -1px rgba(0, 0, 0, 0.06);
  padding-top: 0.75rem;
  padding-bottom: 0.75rem;
  padding-left: 0.75rem;
}

I think it's not recognizing it as a select and just a styled component.

Here is the whole file:

            xl: '1200px',
        },
        fontSize: {
            'xx': '0.550rem',
