What happened with pageAction?
Hi, I'm testing my browser extension on Chrome (48.0.2564.103) and Chromium (50.0.2645.0) and there is strange difference in pageAction feature. As you can on screen for some reason pageAction button in Chromium doesn't show in omnibox as in Chrome:
And also I cannot hide pageAction button in Chromium. If I use hide() function icon turns into grayscale. Can somebody tell me what is happening?

Extensions buttons in your toolbar
Extensions that you can interact with will now display a button icon in the Chrome toolbar. No longer want to use an extension? You can now remove an extension by right clicking on the extension button in your toolbar and selecting “Remove from Chrome.”
Note: Toolbar is found to the right of your address/URL bar (Omnibox).
You can also hide your toolbar extensions in the Chrome menu by right clicking on the extension button and selecting “Hide in Chrome menu.”
Note: you have to individually hide each extension that you don’t want displayed in your toolbar
From the Chrome Menu, right click “Show in Toolbar” to bring a button back to your Chrome toolbar.

Choose a browser action when the extension is relevant to most pages. Choose a page action when the extensions icon should be active or inactive (and grayed out), depending on the page.
