[iOS] Background Color on Text highlights empty spaces and not the actual characters only

[isbaek]

🐛 Bug Report

Putting a background color on long words on iOS highlights empty spaces, if the highlighted words are multi-line and can't fit into a single line.

Attaching screenshots since it's a bit difficult to explain without pics:
iOS iPhone 7

Compare this to the behavior on Android which is expected, correct behavior:
Android

To Reproduce

1. Create a sentence wrapped in Text element
2. Wrap certain long words within the sentence in another Text element with a background color
3. Observe that these long words overflow to the next line and the empty spaces get highlighted on iOS

Expected Behavior

Like Android screenshot above, it should not highlight empty spaces
