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

## What happened

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

```text
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:

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