REGRESSION: controls in a background Safari window maintain active appearance if the address bar has focus

• Component: Forms
• Status: RESOLVED FIXED

Summary:
Mac-themed popup buttons, radio buttons, checkboxes and sliders maintain their "active" appearance (the dark color behind the arrows) in a background Safari window if the window is made background while the address bar has focus.

Steps to reproduce:
1) Go to a URL with a popup, e.g. <data:text/html,%3Cselect%3E%3Coption%3Epick%20me!%3C/option%3E%3C/select%3E>.
2) Click in Safari's address bar.
3) Click on the desktop to send the window to the background.

Expected results:
In step 3, the popup button should lose its active appearance (the dark background behind the arrows).

Actual results:
The popup button maintains active appearance.

Notes:
Those widgets do become inactive if the WebView is first responder when sending the window to the background.

Regression:
This is a regression from shipping WebKit.

Forcing a repaint corrects the widgets' appearance. Using Quartz Debug you can see that if the WebView is first responder when sending the window to the background, the widgets repaint, but if the address bar is first responder, they don't.

(To force a repaint while the window is in the background, have another tab open in the window and command-click that tab to switch to it while keeping the window in the background).

The problem here is that repainting the widgets when the control tint changes is done in Frame::setIsActive. But the rule for when the widgets have active vs. inactive tint is not "is active".

Should not be too difficult to fix. Will require changes to Frame and to WebHTMLView as well.

I think the names "setSecureKeyboardEntry()" and "setNeedsSecureKeyboardEntry()" are confusingly similar.

Also, you probably realize that you could learn of changes to the window's key state by listening to NSWindowDidBecomeKey/NSWindowDidResignKey rather than using _windowChangedKeyState. I presume you chose _windowChangedKeystate for simplicity/performance. Maybe worth a comment.

Typo:
+    // We do a "fake" paintm, and when the theme gets a paint call, it can then do an invalidate.

OK. Maybe I can think of better names.

Actually, _windowChangedKeystate sounds like it's the same thing as NSWindowDidBecomeKey, but it's actually *quite* a bit different. It does just the right thing for control appearance which is way more than just "is this particular window key". I would like to add a comment about that.
