Calling settings page from popup UI issue

Hi. We’re working on the firefox addon and also tried to post it for firefox mobile. There is an issue, when we try to call browser.runtime.openOptionsPage() from popup page, it opens the page in background and popup ui was not closed. That can be confusing because user clicks a button and still can see a popup ui without any notification about new background page. It works well on desktop version because popup UI isn’t in fullscreen mode there.

Any ideas how can we handle this for firefox mobile addon?
