summary_fields in GridField escape html incorrectly about silverstripe-framework

Please provide a text description of what exactly the problem is, and what the expected behaviour is.
Please include any images that help to demonstrate the problem.
Please provide any code as markdown-formatted code blocks rather than images so they can be copy-pasted for easy reproduction.
Please include clear step-by-step instructions for reproducing the bug.

A link to a repository is not a bug report. I'm sorry but the CMS Squad simply doesn't have enough time to look at your repository and figure out for ourselves what the problem is - please spell it out so we can easily prioritise this as appropriate.

Can provide more details if required

Yes, please do.

Please provide a text description of what exactly the problem is, and what the expected behaviour is.

This request is not optional - while I do appreciate you reporting a bug, it is very hard for me to understand what exactly the problem is without you describing what the problem is and what the expected bahaviour is.

Please provide any code as markdown-formatted code blocks rather than images so they can be copy-pasted for easy reproduction.

I have added this request to my earlier comment. Images of code are not useful, because I can't copy them into my IDE to validate I get the same results that you get.

Note that the repository you have provided is not useful to me in identifying what the problem is - I need to be able to understand what the problem is, and reproduce it locally myself from a fresh installation of Silverstripe CMS.

Having taken a glance at the screenshots, it looks like this is probably a duplicate of #11191.

I'm going to close it as a duplicate for now. If it isn't a duplicate, I'm going to need some words that explain to me why not.
