It took me a while to understand what was happening (latest Scriver 3.1.3 11945 on Mac OS Mojave 10.14.6)
I have a list of recommended reading at the end of my book.
Each title in the list (not a style title, just the title and author in a no style paragraph) is formatted that way:
Title by Author, bla bla bla etc…
There is no issue in the binder, but when compiling I noticed that the text stopped abruptly at the end of the title line with the following:
I have other sections where the entries are only in bold, and there is no issue. The problem comes when adding the italics. as well.
For example, I have another section where I have just a film title on a line, with a two letter code in brackets, like this:
Title [AB]
If I have the whole title in bold, no problem, I get this, as expected:
Title [AB]
If I make the title in italics and not the code, like this:
Title [AB]
I have the same issue as above when compiling.
If I display the EPUB in iBooks, the app tells me that there is a mismatch in the formatting code:
error on line x column y: opening and ending tag mismatch: div line 0 and p
Of course, I tried the obvious like getting rid of all formatting and adding the formatting again, that doesn’t make any difference.
The only way to get the ebook to compile is to get rid of the italics within the bold.
I tried changing the font in compile, it doesn’t make any difference.
So it looks like a weird bug to me.
