Strange markup in fieldset header template

Black background - browser's web tools (MS Edge).

Is it ok, that in the result markup the "Orders" is placed after span tag, and span is empty? If I put "Orders" in my own span, then it will be two spans in result - empty one first and then my own with "Orders". Logically it is enough, when there will be only my "Orders" inside legend tag, but what is the purpose of this empty span with rz-fieldset-legend-text style class?

I see it in your editor (fieldset example) and in my code with the latest version of Radzen also.

Another question - is it just as normal to place a pure text inside the HeaderTemplate, without any wrapping tags like <span>, <p>, <RadzenText>, or something like this?

You can check the source code of the component for reference:
