[jordan-th]

Motivation

Ability to exclude certain DOM mutations from affecting the page loading time calculation

Changes

• attributes mutations are ignored if the element has the attribute dd-ignore-mutations
• childList and characterData mutations are ignored if the parent element has the attribute dd-ignore-mutations

Testing

• [x] Local
• [ ] Staging
• [x] Unit
• [ ] End to end
