`v-for` with named `slot` (via `v-for` index) skips first item for 0-based indices · Issue #5480 · vuejs/vue · GitHub

2.2.6

https://codepen.io/Rask/pen/GmZedP

See Codepen. Create a component with a slot repeated over v-for and named with the index, then render the slot elements in the parent component using matching indices. Set the index to be 0..n integers (i.e. a non-associative array).

All elements that are rendered with v-for and slot index should be rendered properly from the parent component data.

The very first element defined with v-for is somehow skipped when rendering.

I'm building a modular repeater field where you can add and remove items which are synced via basic events. The items are slotted in via item indices which are in sync by setting the slot index inside the custom component when rendered inside the parent.

Can this be related to 0-based indices or something? When I replace the slot name with :name="'item' index" the rendering works as expected.
