user: any
expected behaviour: it should be possible to click on the buttons on the detail page when using the Voice Over.
behaviour: When using the Voice Over on Apple Devices the buttons on the idea detail page are not clickable. I can only comment the idea but cannot rate the comments and cannot answer any comments.
important screensize: any
device & browser: iPhone 11, iPhone SE, iPad 8th gen
Comment/Question: the voice over sees the whole detail page as one object (just the function of adding a comment is another object).
