[Feature]: Copy line-wrapped paragraphs without line breaks

[shivaprsd]

Is the feature relevant to the Firefox PDF Viewer?

Yes

Feature description

I have searched past issues and found similar ones, but not one that addresses this exact issue.

Here is the test PDF, it is the same one referenced (long ago) in #7833.

STR

1. Open the test PDF in PDF.js viewer
2. Copy the first few lines of the abstract
3. Paste it in a text editor

Obtained output

Lines are broken as they are wrapped visually:

This paper considers DoS attacks on DNS wherein attackers flood
the nameservers of a zone to disrupt resolution of resource records
belonging to the zone and consequently, any of its sub-zones. We
propose a minor change in the caching behavior of DNS resolvers
that can significantly alleviate the impact of such attacks [...]

Requested behaviour

It would be useful, while copying and pasting, if the lines are not broken but forms a logical paragraph.

OS and browser

macOS Sonoma 14.6, Firefox Developer Edition 133.0b9 (aarch64), PDF.js 4.8.30 [bde36f2]

Other PDF viewers

I haven't checked it in Adobe Acrobat reader.

I will also add a small observation, in case it helps:

I saw it mentioned that <div> was replaced by <span> to aid continuous text selection. But now there are also <br role="presentation"> tags in between the spans, which seems to be the culprit. When I copied two lines after removing the <br> between them, they came together.

But this is not a solution, as it also removes any spaces actually needed between consecutive words in adjacent lines...
