    Description

      After YARN-10826 and YARN-10858, UI2 uses EmberJS 2.8.0, but the refresh buttons do not work anymore. The following error is thrown in the Chrome console, but other browsers also fail.

      yarn-ui.js:38 Uncaught TypeError: Cannot read properties of undefined (reading 'send')
    at Class.refresh (yarn-ui.js:38:311)
    at Class.send (vendor.js:2504:107)
    at Class.superWrapper [as send] (vendor.js:1875:112)

      Downgrading the ember version to 2.7.0 seems to resolve the issue, but this also requires a jquery downgrade.
