[cssom][css-cascade] What should getComputedStyle say for 'line-height: normal' #4249
Description
https://drafts.csswg.org/cssom/#resolved-values
for line-height, it says
The resolved value is the used value.
For a test like this
<!DOCTYPE html>
<input id=input>
<script>w(getComputedStyle(input).lineHeight)</script>

Safari gives 13px, Chrome and Firefox give normal.
Given the definition of used value, I think Safari is correct.
What is correct if we assume "used value" is right?
If CSSOM currently matches Safari, should it be changed to match Chrome & Firefox instead?
