Excerpt not hidden when expanded due to JS error

[Bogardo]

Describe the bug On a view with Mode Display when either the automatic or manual excerpt is enabled, the 'Read more' button shows the full content but keeps the existing excerpt, resulting in duplicate text. This seems to be caused by a Javascript error:

Uncaught TypeError: Cannot set properties of undefined (setting 'display') 
    at HTMLDocument.<anonymous> (readmore.min.jsver=3.0.2:1:1286)

To Reproduce Steps to reproduce the behavior:

1. Create a testimonial with some (long) content

2. Create a view with the following settings:

   

   With style: Default, image on left, light theme, with a quote symbol in the heading Layout: normal Background: inherit from theme Font color: inherit from theme

3. Place view on Page with shortcode

4. Open page with testimonials

5. Click on 'Read more' button

6. See both excerpt and the content of the testimonial

Expected behavior When clicking on the 'Read more' button the excerpt should be hidden and replaced with the full content. Due to the JS error the excerpt is not hidden.
