MARKLESS_ATTRIBUTE_DUPLICATE
Duplicate attribute on one element: a Markless compiler error.
Error from the compiler, while it builds your .tsrx files.
What happened
Markless prints the message, the reason, and a suggestion:
MARKLESS_ATTRIBUTE_DUPLICATE: `<attributeName>` appears twice on <tag>. Only one can win, and render paths can disagree about which value is used.
Duplicate attributes ship invalid HTML and make the element depend on parser and update semantics instead of one authored value.
Keep one `<attributeName>` attribute on this element.Words in angle brackets change from case to case.
How to fix it
Start with the suggestion in the message above.
