BREAKING CHANGES
## Core Components
Removes the `--width` and `--height` variables from the following components, in favor of CSS:
- Button
- FAB Button
- Checkbox
- Removes the `--width`/`--height` and adds a `--size` variable that is set on the width and height, allowing width and height to still be set and border-radius to still use it as a variable
- Radio
- Removes the `--width`/`--height` and `--inner-width`/`--inner-height` variables. Calculates inner values based on parent element size.
## Overlay Components
The following components have all be converted to shadow (or scoped) and have CSS variables for width/height:
- Action Sheet _(scoped)_
- Alert _(scoped)_
- Loading _(scoped)_
- Menu _(shadow)_
- Modal _(scoped)_
- Picker _(scoped)_
- Popover _(scoped)_
- Toast _(shadow)_
The above components will now have the following CSS variables for consistency among overlays:
| Name |
| ----------------- |
| `--height` |
| `--max-height` |
| `--max-width` |
| `--min-height` |
| `--min-width` |
| `--width` |
If the component does not set the value, it will default to `auto`.
