Cannot receive drag and drop events after enterFullScreenMod

[fcherny]

I'm running CEF 3.3163.1671.g700dc25 and have run into a problem. I'm wondering if anyone has experience with this or has a work-around.

Basically, when I enter full screen mode (on a Mac), I stop receiving drag and drop events. Specifically, it happens when I run this api to enter full screen mode:

self.mContentView = [(AppDelegate *)[[NSApplication sharedApplication] delegate] window].contentView;

NSApplicationPresentationOptions options =
NSApplicationPresentationDisableAppleMenu |
NSApplicationPresentationDisableForceQuit |
NSApplicationPresentationDisableHideApplication |
NSApplicationPresentationDisableProcessSwitching |
NSApplicationPresentationDisableSessionTermination |
NSApplicationPresentationHideDock |
NSApplicationPresentationHideMenuBar;

[self.mContentView enterFullScreenMode:[NSScreen mainScreen] withOptions:@{NSFullScreenModeApplicationPresentationOptions : @(options) }];

After that, I don't see any calls to the OnDragEnter handler. If I simply do
[self.mContentView enterFullScreenMode:[NSScreen mainScreen] withOptions:nil];
drag and drop still works.

I feel like I'm missing something obvious. Any ideas on how I can debug this would be appreciated as well.

After further investigation, it's this command that was disabling drag and drop:
[[(AppDelegate *)[[NSApplication sharedApplication] delegate] window] setLevel:1000000];

Apparently the value 1000000 is invalid, which results in this peculiar side effect.
