Clipboard preference orders prefers text/html over UTF-8 when using plain-text

[zusorio]

When I try to copy some text that's only available as UTF-8 and text/html, text/html is preferred when I have plain-text selected as preferred. I think copying the text as UTF-8 would be the more expected behavior.

text that's only available as UTF-8 and HTML5

Do you mean text/html?

Do you have an example app I can use to test this?

Yup, sorry I meant text/html

Do you have an example app I can use to test this?

Yes, it's a bit involved but here's a full reproduction

• Use this to start the container

docker run \
  -e CONNECTION_METHOD=xpra \
  -e AUTOSTART_CAPELLA=1 \
  -e XPRA_SUBPATH=/xpra/ \
  -p 8888:10000 \
  -v /workspace \
  ghcr.io/dsd-dbs/capella-dockerimages/capella/remote:7.0.0-selected-dropins-main

• Open http://localhost:8888/xpra/
• In Capella, click on File > New > Capella Project
• Name it test and click Finish
• Expand test > test.aird > test > Logical Architecture
• Right click on Capabilities, then Add new Capella Element > Capability Realization
• Double-click on CapabilityRealization1
• Put some text in the Pre-Condition field
• Copy the text -> It's copied as HTML despite the clipboard preferred format being text/plain
• Go to http://localhost:8888/xpra/?clipboard_preferred_format=UTF8_STRING and try again, now the text is copied correctly

Let me know if that reproduction works for you

That's way too complicated for me to test.

I need a simple test application, no containers.
