[Bug] Low contrast selection field with disabled attribute

[tringuyenduc2903]

Bug report

What I did

Create a select field

        // type: relationship (BelongsTo)
        CRUD::field('user')
            ->label(ucfirst(trans('validation.attributes.customer')))
            ->attributes(['disabled' => 'disabled']);

What I expected to happen

In Dark theme, with disabled attribute, users can monitor old data

What happened

In Dark theme -> Bad

In Light theme -> Good

What I've already tried to fix it

Edit css

Is it a bug in the latest version of Backpack?

After I run backpack composer update backpack/crud the error it still persists

Hey @tringuyenduc2903

When I disabled the select field, it was different than yours in the dark theme. But yes, there is an issue...

@pxpm In my test, enabled and disabled fields have no visual difference in the dark theme.
