Feedback for “Tour options”

Description

Unclear/incorrect doc

buttonClass says

Additional classes to put on the buttons
Default: ""

But it seems to be replacing thi introjs-button class as well as adding in classes

Expected Behavior

The docs say, that buttonClass adds additional classes, but doesn't mention that it removes the introjs-button class.

Is it a bug that it is removing it? Or are the docs incorrect?

Locally, I'm just adding introjs-button into buttonClass to deal with this.
{ buttonClass: 'introjs-button an-additional-class' }

but thought it would be worth mentioning it.

It could be related to this issue #1700

Actual Behavior

But putting
{ buttonClass: 'an-additional-class' }
seems to be replacing the base button class

<a role="button" tabindex="0" class="an-additional-class introjs-nextbutton">Next</a>
compared to without buttonClass set

<a role="button" tabindex="0" class="introjs-button introjs-nextbutton">Next</a>

Example (recommended)

use {buttonClass: 'an-other-class'} in introjs options object

Environment (optional)

Brave browser Version 1.69.168 Chromium: 128.0.6613.138 (Official Build) (64-bit)

Thanks

Thanks for running this codebase and the amazing product that it is.
Happy to run a PR once I know whether the code or the docs are correct
