Twenty Nineteen: button block font size issue.

[nidhidhandhukiya]

Steps to reproduce:-

1. Activate Twenty Nineteen Theme.
2. Choose button block.
3. Change the font size of the button.
4. Check at the Front side.

You can see the font is a little lesser than our given font size.
The font size is exactly the same on our editor side but the front side font is lesser than the given font-size value.
I have attached video for better understanding.

Resets the relative measurement on .wp-block-button__link when either its Buttons or Button block has a custom size. Without this change, the value is 88.9% of the selected size.

The first patch would increase the default size to 22px.

PR 6511 only changes the value when the Button or Buttons block has a custom size.

56443.patch would increase the default font size for Button block links.

Please test PR 6511 (​6511.diff) to verify that

1. the default font size is still 0.88889em (19.55556 pixels) and
2. custom and preset font sizes, whether set on the Buttons or Button block, will match what was chosen.

Twenty Nineteen: Resolves button block font issues.

The font on buttons was displaying less than the font size when applied through the editor. This resets the relative measurement on wp-block-buttonlink when either its Buttons or Button block has a custom size.
