TextInput `setSelection` "ignored" when TextInput has gone out of focus

Description

When assigning a ref to TextInput there is a setSelection method, which in general works great for changing the selection of the input, without needing to set a selection prop.

However, on android, there is an edge case where when the TextInput has gone out of focus while calling setSelection the new selection is ignored.

See this video, where we have simple code that adds an emoji in the place of the selection:

Now we changed the code a bit and the TextInput will actually lose focus while we are changing the text. You can see that the selection is wrong. We said the selection to have a range of 0, but it still has the previous range:

I see how I could fix this by using a selection prop. But this would cause other issues. I could see how I can hack my way around it by further waiting before I call setSelection, however, this can create UI glitches.

I would just assume it to work when I called setSelection.

On iOS something similar can be observed. Here the selection cursor gets set to the end (although onSelectionChange isn't reporting necessarily a change, there is one):

Steps to reproduce

• Clone the repository
• Run yarn
• Run yarn android
• When the app opens, click inside the TextInput and select any text
• Then click on "Open emoji modal"
• Click on "Add emoji"

Important note: I assume this bug is a race condition as it doesn't happen 100% of the time you try!
