MARKLESS_SPREAD_STATIC_SNAPSHOT

Spread attributes render once: a Markless compiler warning.

Warning from the compiler, while it builds your .tsrx files.

What happened

Markless prints the message, the reason, and a suggestion:

MARKLESS_SPREAD_STATIC_SNAPSHOT: {...<spreadSource>} copies attributes during initial render. When <spreadSource> changes later, these attributes do not update.
The compiler plans DOM-update records for graph-backed attributes it can see; a spread hides which attributes exist, so no update records are planned for it.
Bind attributes that change individually, such as <div id={menu.id} data-open={menu.open} />, and keep the spread only for initial attributes.

Words in angle brackets change from case to case.

How to fix it

Start with the suggestion in the message above.

If you accept the warning on purpose, put this comment on the line above it:

// markless-allow MARKLESS_SPREAD_STATIC_SNAPSHOT: the reason you accept it
