unsafe pre-fix added to url in mashup after upgrade to Qlik Sense November 2018

[rbartley]

Hi everyone,

After upgrading to Qlik Sense November 2018, my custom back button  (see snippet below) has stopped working as the href attribute is being prefixed with "unsafe".  

<a id='butClose' class="indicatorCloseButtonA closeButtonWhite" href='javascript&colon;top.history.back();' target='_parent' onclick='closeChart();'>...</a>

After a bit of searching, I found that this could be linked to an upgrade in the Qlik Sense of Angular.js .

I have found this page: https://anotherdevblog.com/2018/06/27/angularjs-adds-unsafe-before-links/ but I have no idea how to apply the solution.  Can anyone help?
