Introduced with marked v15.

[silamon]

Like mentioned above, we use marked to render markdown strings. It was recently upgraded, can you test on https://marked.js.org/demo/ ?

• Latest stable HA 2024.11.3 is on marked version 14.1.4, I assume that works since you mentioned that it works on latest stable.
• Beta HA is currently on marked version 15.0.2, the demo shouldn't display anything at all on that version.
• Latest marked version is 15.0.3, which contains a fix for invalid regexes. If it displays correctly in the demo, we should upgrade.

[Bram-diederik]

Sure thing will check.

[Bram-diederik]

15.0.0 works after that no render.
Do i need to make a bug there?

for now for my main laptop i could integrade more cards for my widgets in the local docker hass and dont update that.
but for my roaming given laptop (i use now) there is no alternative.
Its an hp stream with budget specs but a very good batttery (for budget)

falkon is way faster browser then chrome and firefox i use normaly.

[Bram-diederik]

already known in markedjs: browser is to old.
markedjs/marked#3546 (comment)

[Bram-diederik]

Kde6 is not even in debian unstable.

[bramkragten]

That specific issue doesn't seem to be the issue you see in HA, (we do polyfill for older browser), lets bump to 15.0.3
