Space lost between sub and sup tags

[rbreu]

(Using Nokogiri 1.5.0)

For almost all inline tags, Nokogiri preserves space between subsequent tags, as I'd expect it to:

irb(main):004:0> Nokogiri::HTML.fragment("<em>a</em> <em>b</em>").to_s
=> "<em>a</em> <em>b</em>"

However, between sup and sub tags, the space gets lost:

irb(main):002:0> Nokogiri::HTML.fragment("^a ^b").to_s
=> "^a^b"

irb(main):003:0> Nokogiri::HTML.fragment("_a _b").to_s
=> "_a_b"

Since it makes a difference when displayed in the browser whether the space is there or not, this looks like a bug to me?

Hello!

Thanks for asking this question!

Unfortunately, this behavior is dependent on the underlying libraries -- there's not much we can do in Nokogiri to change serialization conventions. :(

Sorry we can't do much for your problem, but thanks for using Nokogiri.
