[ios] Fixes a 0.5s delay when entering or exiting the tab grid.

On iOS 15, snapshotting views with afterScreenUpdates:YES waits 0.5s for
the status bar style to update. Work around that delay by taking the
snapshot first and then triggering the tab grid animation afterwards.

This bug was visible in scenarios where entering or exiting the tab grid
required a status bar style change -- specifically, light mode
non-incognito BVCs.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
