Tag-based annotation: missing spaces sometimes#298

On nest 151, I imported the study Zha 2020 (32652163) via unpaywall. When I test out the tag-from-highlights feature, the spaces are missing (see attached).

This behavior was also observed in the study de Macedo 2020 (32776930), but it did not occur in Townsend 2020 (32864608), which was also imported via unpaywall.

P.S. I like the copy PMID to clipboard feature :)

Got it, thanks! Going to check if this is out of our hands or not (may be upstream of anything we control).

Hi all, this occurred this morning for me as well in multiple studies.

Thanks! This must be a property of the PDF’s display. We’ll take a look!

Kristen - Kathryn hasn’t shared her nest with me - could you let me know what nest you’re in and the study/publication exhibiting this?

Yep, I am in this nest https://nested-knowledge.com/gather/tagging_inspector/1272

This article is Baek, 2021

Could you add the NK org or add me as a user? Thanks! (I prefer not to subvert our authorization system by accessing data from the backend)

Sounds good Karl, thank you for the help!

To keep everyone abreast of progress, albeit with too much technical detail, I’m 90% confident we’ve figured out a solution. The open source annotation library we use is bumping its PDF renderer, which critically will include an improvement to how it chunks up pieces of text with whitespace between. I verfied this change fixes Baek 2021 and can preemptively check other examples if you’d like to attach or email me a PDF!

Since we aren’t directly in control of when the improvement will get a production release, I can’t promise when this will be fixed. The maintainer seems active & receptive to help, so we’ll do our best to assist a fast release.

Thanks for the detailed response!

FYI - we should have the fix out in next release, Thursday or Friday of this week. Unfortunately, this will result in some degradation for firefox users (which we decided is less important than this fix in Chrome, and will be fixed in a future release).

The fix is in with release 1.33.0- please let me know what you think of the results! Note:

• We still have some trouble with spaces on line wraps. I’m looking into a solution for this in the upstream.
• Multiline selections may look off in certain cases in Firefox (only). I’m tracking this in the upstream here.
