Ratings element broken in 1.8.50

Bug

What is the current behavior?

For a basic "rating" page element in version 1.8.50, the survey page renders the rating elements, and NONE of the numbers are selectable by the user. No errors are displayed in the Browser console. The comment box can be filled out but the next button CANNOT be clicked because a number (rating) has not been chosen.

What is the expected behavior?

The survey page renders the rating elements, and any of the numbers are selectable. The comment box can be filled out and the next button can be clicked. This is the behavior in 1.8.49

How would you reproduce the current behavior (if this is a bug)?

Provide the test code and the tested page URL (if applicable)

For the config:

{
    "title": "Foo Survey",
    "pages": [{
            "name": "Bar Page",
            "elements": [{
                "type": "rating",
                "name": "Baz Score",
                "title": "Please rate!!!",
                "isRequired": true,
                "hasComment": true,
                "commentText": "Please explain your rating:",
                "rateMin": 0,
                "rateMax": 10,
                "minRateDescription": "Not likely at all",
                "maxRateDescription": "Very likely"
            }],
            "title": "Overall"
        }]
}

@bbbco It works for me. Here is the example. I have checked our example in all platforms and themes.

PS: We have several E2E tests on "rating" question.

Thank you, Andrew

Here's a fork of your example matching what our code looked like when the 1.8.50 release broke ratings: https://plnkr.co/edit/JnPJgVWgsnCfeBxb

Did a little more looking, and it is now obvious that when using knockout, survey-library 1.8.50 is only compatible with knockout 3.5.x. Anything earlier than that breaks the ratings element.

[andrewtelnov]

@bbbco Got it. We moved to knockout 3.5.1 because of SurveyJS Creator some times ago. All our examples and E2E tests using this version. Could you migrate to v3.5.1?

Thank you, Andrew

[bbbco]

Yes, I was able to migrate to knockout 3.5

Is there some sort of compatibility matrix that needs updated?

I updated our npm packages and require knockout v3.5.1+

Thank you!
