Fixes #5831.

iOS 15 has a significant crashing bug whereby use of a canvas element
completely crashes the browser in some contexts. In particular, we have
observed this when using a WKWebView in a keyboard extension without
'Allow Full Access' switched on.

Keyman uses canvas element to draw a nice looking key preview (key tip)
on iPhones. This is a critical issue for Keyman for iPhone. Keyman for
iPad is not affected because the iPad version does not use key previews.

The resolution here is to remove use of the canvas drawing for key tips
and use a simplified pure HTML/CSS shape. I have not conditioned this
fix on platform; I have currently opted to apply this to all platforms.

This issue will be reported to Apple for resolution. The issue applies
so far to iOS 15.0, 15.1.
