1532277 - Reader mode omits seemingly-random small parts of large gnu.org manual page

Status: NEW

(Toolkit :: Reader Mode, defect, P5)

Description

[[:nickname] blackmonkmeme]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:65.0) Gecko/20100101 Firefox/65.0

Steps to reproduce:

Firefox Reader View is sometimes blank where it should be displaying text.

E.g.

Go to web page for the GNU Grub manual:

https://www.gnu.org/software/grub/manual/grub/grub.html

Then select <alt><V><R>, to select Firefox Reader View

Actual results:

See the code snippets in section 2 ("Naming convention"), and section 3 ("OS-specific notes about grub tools").

Reader View does not reproduce the code snippets in section 2. Likewise, it fails to reproduce some of the code snippets in Section 3. Yet it doesn reproduce some of the section 3 code snippets faithfully.

At a glance, there is no obvious difference between those snippets it reproduces and those it does not.

Expected results:

It should have displayed all the code snippets.

Portions of text like # grub-install /dev/sda are missing from reader view.

This is ultimately a readability issue. I don't know off-hand what's causing it, though it might be related to the use of <kbd> ? I don't know why though. I filed https://github.com/mozilla/readability/issues/528 .
