Previously we merged #142930, to solve issue #87061.

Since then, I discovered that the keyboard input wasn't being captured after the app had been paused and resumed. After some digging, I realized that the problem was due to [a line in editable_text.dart](https://github.com/flutter/flutter/blob/d4b1b6e744ba6196e14fb49904f07a4aea4d5869/packages/flutter/lib/src/widgets/editable_text.dart#L3589) that called the `focusNode.consumeKeyboardToken()` method.

Luckily, it's a very easy fix: we just use `requestFocus()` instead of `applyFocusChangesIfNeeded()`. @gspencergoog could you take a look when you have a chance?
