Links "disapear" when editing Word document in Collabora

[CBra-GPE]

Describe the Bug

When we edit an existing Word file with links in it, the links stop appearing as links afterwards. Also when you open the document in Word, but Ctrl + mouse click still works in Word.

Steps to Reproduce

1. Open the attached document in Collabora online
2. Edit the document (insert space and remove it again is sufficient)
3. Save it and close the dialog (i.e. ensure PutFile is called)

Expected Behavior

The links in the document will continue to appear as links. I.e. the underline and blue color stays the same for links.

Actual Behavior

Links now look like regurlar text, also when opening the document in Word. The links still work though, it's just the appearence that is broken.

Desktop

(Please complete the following information)

• Collabora version: 25.04.2.1.1
• OS and version: Windows 11
• Browser and version: WebView2 136.0.3240.92

Additional Context

I have attached to documents to showcase the issue.

@CBra-GPE thanks for the report. On what software do you open the file after step 3 of your ticket?

Microsoft Office? Libreoffice? Collabora Online? And what versions of said software?

[CBra-GPE]

@jazevedo-coll the links are gone in all three programs. If I open the document again in Collabora Online or when I open the document in Microsoft Word (Microsoft® Word til Microsoft 365 MSO (Version 2504 Build 16.0.18730.20186) 64-bit ). They are also gone when I open the document in LibreOffice Writer (Version: 25.2.3.2 (X86_64)).

So to be clear, I create a document with links in Word, open set document in Collabora Online, edit the document, without touching the links. Afterwards when I open the document in Word or LibreOffice Writer or Collabora Online the links are missing.

I don't reproduce the issue with Collabora Online 25.04.3.2 or libreOffice 25.2.4.3.

I just tried again after upgrading Collabora to version 25.04.4.2.1, it's still an issue for us. I have attached a gif showing what we experience.

I have the problem with documents created with Collabora (version 25.04.6.1): links styles are disappearing after a time. If I redo the styles on those links, they will disappear again later. That's a big problem to identify them in documents.

I noticed that if I create a new link, its styles will be disappearing later than previous links. I don't know if it's about duration or number of modifications on the file. That's strange.

For us, the problem only occured when changing language of Collabora. By setting "lang=da-DK" in the WOPISrc.

Here, Collabora is in French (but it's not my server so I can't test removing this setting).
