Jenkins 2.539+ has a built-in Content Security Policy feature.

Docs: https://www.jenkins.io/doc/book/security/csp/ 

This plugin is not compatible with it yet due to:

• https://github.com/jenkinsci/matlab-plugin/blob/9bfbb7b29b5feaf5f826ddfba35355c318d66894/src/main/resources/com/mathworks/ci/TestResultsViewAction/index.jelly#L149
• a number of onclick event handlers around https://github.com/jenkinsci/matlab-plugin/blob/9bfbb7b29b5feaf5f826ddfba35355c318d66894/src/main/resources/com/mathworks/ci/TestResultsViewAction/index.jelly#L11-L121 

As a result, admins have to choose between this plugin working, and improved security.

This plugin should be made compatible with CSP and its code rearranged.
