    In our react project we have used @progress/kendo-react-grid module and set content security policy as style-src 'self'.  
    has dependency on Kendo-react-popup and that package is using inline style which violates content security policy. What is the best solution to overcome this issue or is there any version available for the same package without inline style.

    Have attached screen shot of that function and We are getting below console error:

    util.js:97 Refused to apply inline style because it violates the following Content Security Policy directive: "style-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-Y+wsDh+eE='), or a nonce ('nonce-...') is required to enable inline execution.

    Hello, Vikram,

    This is currently expected as the Popup and some other components, like the Window for example have a dynamic position that is controlled via the top and left styles.

    The unsafe-inline has to be used.

    We understand that this not ideal, but there is no other option to dynamically set the position of an HTML element. If such an option is available we will review it and discuss an optimization.

    Apologies for the inconvenience this may have caused you.
