A lot of these are caused by the SanitizationFilter of HTML::Pipeline doing its job.

I can't think of a good way to escape_once the user's input text to allow things like This is text < This is more text and Using <placeholders> for text without breaking the option for users to enter certain raw HTML tags.

In other words, right now I think these two things are mutually exclusive:

1. Getting This is < text to render as This is < text
2. Getting This should be <b>valid</b> to render as This should be <b>valid</b>

I'll continue investigating these, though.

Thanks for looking into this @razer6

Sorry, it's no argument, but: "on other sites this is working" (somehow)

Maybe whitelisting some tags by introducing an escape sequence before escaping all HTML tags and then remove the escape string again. However, it must be assured that this special escape sequence does not occurr in normal text (such as done in https://en.wikipedia.org/wiki/Bit_stuffing)

mentioned in issue #1429 (closed)

It looks like #1378 (closed) isn't actually related to this. Is it ok if I remove that from the list in this issue's description?

@razer6 yes, that's fine

Closing this one, since there is only one open issue in that list.

Status changed to closed
