- **fixed** — Fix DOM.sanitize leaving dangerous attributes behind when multiple consecutive attributes are present by iterating over a copy of the attributes list instead of the live NamedNodeMap
- **fixed** — Give custom layers the live globe transition in CustomRenderMethodInput.defaultProjectionData.projectionTransition instead of using a hardcoded value of 1

###### 🐞 Bug fixes

- Fix `DOM.sanitize` leaving dangerous attributes behind when multiple consecutive attributes are present. Iterating the live `NamedNodeMap` from `elem.attributes` while calling `removeAttribute` skipped the attribute directly after a removed one, so a second dangerous attribute (for example an `ontoggle` on a `<details open>` element) could survive sanitisation and later execute ([#8189](https://github.com/maplibre/maplibre-gl-js/pull/8189)) (by [@0xKirisame](https://github.com/0xKirisame))
- Give custom layers the live globe transition in `CustomRenderMethodInput.defaultProjectionData.projectionTransition`, which was hardcoded to 1 for the whole globe/mercator transition, so a custom layer jumped straight to the fully bent globe while every other layer eased ([#8169](https://github.com/maplibre/maplibre-gl-js/pull/8169)) (by [@mondsichtung](https://github.com/mondsichtung))
