More testing in Chrome.
The data retrieved by the json request IS being filled into the elements on the page. Inspecting the iframe of the extension shows everything is fine. In fact, I can select all within that iframe on the player and copy the contents, it’s just not visible. Links that are in the extension are clickable, just not visible.
Also, since it’s in a hosted test, I have to click ACCEPT one initial load. If I click ACCEPT and do not move my mouse, the initial page is visible, as soon as the mouse moves it disappears. This is extremely odd behavior.
Can anyone point me in a direction?
