    If you add rich text tags to UIElement they are not parsed, but layout is calculated as if they are there.
    Code (CSharp):
    1. Label label = new Label("<color=#FF00FFFF>coloured</color>");
    2. label.ClearClassList();
    3. label.style.alignSelf = Align.FlexStart;
    4. rootVisualElement.Add(label);
    Now we have a label that's the size of the word "coloured" but we actually have the entire label text still in it!
    I'd love a non-hack way to turn off this behaviour whilst it's only partially implemented. I've only managed to recalculate and set the intended size of the text using a load of reflection hacks.


    I'm also regularly getting asserts that are spamming the console from what I can only assume are certain types of nested content:
    Logs presented are from 2019.1.0a12

    This is clearly a bug (both the rich text tags causing the text to wrap and the remaining UIR asserts). Please submit them as bugs. You can do this right from Unity (that's easiest) using the Bug Reporter.

    Correct, RichText tags will only be supported at the end of 2020.

    That said, there is a bug reported, which was previously closed but was re-opened, which should be fixed sooner and might get a backport to 2019.3.
    https://issuetracker.unity3d.com/is...-was-clicked-when-whitespace-is-set-to-normal

    This seems like a duplicate of 1115452 (reported above) - as in the fix for one should fix the other. CORRECTION: 1115452 appears to be fixed in 2019.3.

    To reiterate:
    1. Actual RichText tags support will not come until late 2020.
    2. Bugs related to RichText tags are being tracked and might get backported.

    I'm more confused now! So they right now should work (and buggy), but are not supported?

    They are currently not supported which means they should "do nothing". However, UI Toolkit (formally UIElements) shares some of the text backend with IMGUI and uGUI and that backend does know about RichText tags. This is causing bugs where parts of the code know about tags, others don't.

    So, right now, the tags should do nothing (including not causing bugs). In the future, they will change the styling of the text as expected.
