response-area-height doesn't appear to have any effect

[colvinco]

Hello,

https://rapidocweb.com/api.html#att-layout describes response-area-height as follows:

response-area-height	Allowed: valid css height value such as 400px, 50%, 60vh etc - Use this value to control the height of response textarea	300px

It was added for #110 , but it doesn't appear to do anything

Looking through the source, it is picked up:

1. responseAreaHeight: { type: String, attribute: 'response-area-height' } - https://github.com/rapi-doc/RapiDoc/blob/master/src/rapidoc.js#L64
2. --resp-area-height: ${this.responseAreaHeight}; - https://github.com/rapi-doc/RapiDoc/blob/master/src/utils/theme.js#L208

.multiline {
    overflow: scroll;
    max-height: var(--resp-area-height, 300px);
    color: var(--fg3);
}

https://github.com/rapi-doc/RapiDoc/blob/master/src/styles/font-styles.js#L43

However multiline doesn't appear to be used as a class on the response areas (or anywhere else?). If I apply the multiline class to a response area then the setting does limit the height as expected.

Am I missing something or is this a bug?
