Describe your issue

We are using ViewComponent to manage our HTML templates.

With a ruby template like this:

class FooComponent < ApplicationComponent
  def call = tag.span "Foo", class: %w[rounded-full h-0.75 w-0.75]
end

The generated Tailwind styles include rounded-full, h-0.75 but not the w-0.75-class.

When re-arranging the css classes like so:

class FooComponent < ApplicationComponent
  def call = tag.span "Foo", class: %w[rounded-full w-0.75 h-0.75]
end

The generated Tailwind styles include include rounded-full, w-0.75 but not the h-0.75-class.

When re-arranging the css classes like so:

class FooComponent < ApplicationComponent
  def call = tag.span "Foo", class: %w[w-0.75 h-0.75 rounded-full]
end
``

The generated Tailwind styles includes all expected classes (`rounded-full`, `h-0.75` but and `w-0.75`).
