[josieg]

Prerequisites

• [ ] Are you running the latest version of Pressbooks, the latest version of McLuhan, and the latest version of WordPress? - No, BCcampus is behind
• [x] Are you experiencing the issue while using this book theme?
• [x] Did you perform a cursory search to see if your bug or enhancement is already listed?

Description

Paragraphs inside textboxes (except for the first) that have class="hanging-indent" do not display correctly in PDF exports, EPUB, and MOBI files. The webbook is okay.

Steps to Reproduce

1. Create a textbox.
2. Add a few paragraphs to the textbox.
3. Apply "Hanging indent" to all paragraphs.
4. Export chapter as PDF, MOBI, EPUB.

Expected behavior: I expect the appearance of hanging indents to match the webbook:

Actual behavior: Here is a screenshot from the PDF file. All paragraphs in this screenshot have class="hanging-indent", but the second and third paragraphs inside the textbox are displaying incorrectly:

@dannylonglegs Can you check this out? Thanks for the report, @josieg!

Confirmed reproducible, except that in themes tested (McLuhan and Malala) the first hanging indent would not format correctly either.

It's likely that all indentation formats are affected, since I'm seeing similar issues with the "No-indent." That would include paragraph classes "indent", "no-indent" and "hanging-indent".
