Extension API: chrome.browserAction.setIcon w/ imageData

[jonathansampson]

Describe the issue you encountered:
Brave's implementation of chrome.browserAction.setIcon does not presently support imageData objects. As a result, the following (taken from the Vimium extension) fails:

chrome.browserAction.setIcon({
  tabId: tabId,
  imageData: (function() {
    var enabledStateIcon;
    enabledStateIcon = !enabledState.isEnabledForUrl ? DISABLED_ICON : 0 < enabledState.passKeys.length ? PARTIAL_ICON : ENABLED_ICON;
    return iconImageData[enabledStateIcon];
})()

Expected behavior:
Brave should accept imageData objects as an argument to chrome.browserAction.setIcon.
