1703314 - reader view works for the URL mentioned below, but I did manage to spot one line that is not displayed

Status: NEW

(Toolkit :: Reader Mode, defect, P3)

Description

[u34]

Attachment: Screenshot_2021-04-06 6 The Exim runtime configuration file.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0

Steps to reproduce:

The form allowed me to attach a single file. I want to attach 2 files. Hopefully, I will be able to attach another file in a comment, or something.

1. Browse to http://exim.org/exim-html-current/doc/html/spec_html/ch-the_exim_runtime_configuration_file.html#SECTempitelis .
2. Have the "22. Empty items in lists" title in the middle of the screen. As in the attached 'Screenshot_2021-04-06 6 The Exim runtime configuration file.png' .
3. Note that few lines below the title "22. Empty items in lists" there is a line that reads:
   senders = user@domain :
   Also note this line has a colored background, which is different from the white background color of most of the text. Yet there are other lines with the same background color as the "senders = user@domain :" line.
4. Now toggle to reader view. Perhaps with Ctrl+Alt+R key combination, or by the button to the left of the URL.
5. Within reader view obtain the "22. Empty items in lists" title in the middle of the screen. Perhaps by scrolling upwards or downwards. Similar to the attached 'Screenshot_2021-04-06 6 The Exim runtime configuration file, reader view.png' .

Actual results:

The text in reader view seems to be displayed as expected. In particular, the lines that had another background color in the regular view are also present in the reader view, albeit without the different background color. Which is probably as designed. However, the single line with the
senders = user@domain :
text is missing in reader view.

Same issue observed in Linux and in Windows 10.

Expected results:

All the text should have been displayed in reader view. Including the
senders = user@domain :
line.

I referred to this file in my original description of the bug. But could not attach more than 1 file to my original report.

(In reply to u34 from comment #1)
The reader view button is to the right of the URL, not to the left of it, as stated earlier.

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Toolkit::Reader Mode' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Thank you for filing this bug. Issues with the parsing algorithm are generally tracked in the Github project. I've duplicated your bug there, https://github.com/mozilla/readability/issues/688
