Vertical align not working in combination with rowspan

I am hopefully not making a silly mistake, but I can't work out how to vertically align a cell with a rowspan correctly.

Here my minimal example:

require "prawn"
require "prawn/table"

Prawn::Document.generate('rowspan-valign-bug.pdf') do
  table [
    [{ content: "Foo", rowspan: 2, valign: :center }, { content: "1" }, { content: "2" }],
    [{ content: "3" }, { content: "4" }]
  ]
end

The output then looks like this:
rowspan-valign-bug

Am I missing something, is this expected behaviour or actually a bug?

To make sure I understand correctly, you expect 'Foo' to appear a little higher, correct? So that the spacing above and below the letters are more similar?

Yes, I expect the capital letter to be centered with the horizontal line on
the right side. But it seems like the 'Foo' starts right below of the line

To make sure I understand correctly, you expect 'Foo' to appear a little
higher, correct? So that the spacing above and below the letters are more
similar?

Yep I agree that looks like a bug. If you (or anyone else) has the time feel free to dive in and try to sort it out. I'm not sure when I'll get the chance but if I do I'll update the issue.

I have the similar problem.
I wanted to dynamically, it gives a table mix
