[csswg-drafts] [css-pseudo-4] ::first-letter should include space separators (#5154)

johannesodland has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-pseudo-4] ::first-letter should include space separators ==
Some languages requires a space separator between the first-punctuation and the first letter. Both the punctuation and the space separator should be included in the ::first-letter pseudo element.

Browsers treat this differently at the moment. Safari includes spaces, while Chrome does not. 
https://bugs.chromium.org/p/chromium/issues/detail?id=638267.

At the moment the spec does not specify that space should be included: https://www.w3.org/TR/css-pseudo-4/#first-letter-pseudo

Examples: 

**French**
The opening quotation mark in French cannot go without a space: 
« Voulez-vous un sandwich, Henri ? »

**Norwegian**
Some quotation marks in Norwegian (replikkstrek) cannot go without a space: 
– Pettersen, ropte hun, – kom inn og få kaffe.
