• Previously, any each block parents were used as keys for the sub group. That's wrong, it should only be using each blocks whos declarations contribute to the bind:group expression. Fixes Svelte 5: Nested {#each} causes bind:group to improperly clear #10345
• Only the left-most identifier of the expression was used to determine the binding group. This is wrong, all identifiers within the expression need to be taken into account. Fixes Svelte 5: bind:group incorrectly considers other groups when changing value #9947
