Methods

Name	Description
`checkValidity() => boolean`	Returns `true` if the textarea passes validity checks. Returns `false` and fires an `invalid` event on the textarea otherwise. NOTE: When accessing any property or function that checks validity at textarea initial boot up, you may have to await `<fwc-textarea>.updateComplete`.
`reportValidity() => boolean`	Runs `checkValidity()` method, and if it returns false, then it reports to the user that the input is invalid.
`setCustomValidity(message:string) => void`	Sets a custom validity message (also overwrites `validationMessage`). If this message is not the empty string, then the element is suffering from a custom validity error and does not validate.
`layout() => Promise<void>`	Re-calculate layout. If a textarea is styled with `display:none` before it is first rendered, and it has a label that is floating, then you must call `layout()` the first time you remove `display:none`, or else the notch surrounding the label will not render correctly.
