Same Mark.Id for blocks after text blocks

[b0oh]

When using Mark.withId I found that it gives same id's for blocks that coming after text blocks.
Example is here: https://ellie-app.com/6DnZGxT3Rvda1

elm=0.19
elm-markup=3.0.1

In example we can see that two blocks have id=7, and the next two have id=9.

Actually, in example, even if you replace text blocks with

|> Paragraph
    Lorem ipsum dolor

and add such a block, it still will produce same result with repeating id's.
