autoCapitalize does not work when a placeholder is specified.

Bug

What's the current behavior?

When a placeholder is provided the editor does not respect the autoCapitalize attribute. Focusing and typing in an editor with autoCapitalize="sentences" does not auto capitalize the start of the first sentence. When the editor does not contain a placeholder, the behaviour is as expected.

Example: https://d5vw9.csb.app/

Browser: Safari (mobile) OS: iOS 13.6 Slate: 0.59.0

What's the expected behavior?

The first character of the initial sentence is auto capitalized, like when no placeholder is specified.

The placeholder also seems to break autoFocus.

I'm running into this too. Does anyone know of a workaround for this issue?
