Target is missing for all mutation records

[sionzee]

Actually when you receive a MutationRecord from observer, there should be a specified target property.

At happy-dom the target is missing everywhere and that makes MutationObserver unusable.

there are few locations where I noticed the target is missing:

• happy-dom/packages/happy-dom/src/nodes/node/Node.ts

  Line 271 in a853a6f

  record.addedNodes = [node];

• happy-dom/packages/happy-dom/src/nodes/node/Node.ts

  Line 307 in a853a6f

  record.removedNodes = [node];

• happy-dom/packages/happy-dom/src/nodes/node/Node.ts

  Line 372 in a853a6f

  record.addedNodes = [newNode];

• happy-dom/packages/happy-dom/src/nodes/element/Element.ts

  Line 803 in 78210cf

  const record = new MutationRecord();

• happy-dom/packages/happy-dom/src/nodes/element/Element.ts

  Line 879 in 78210cf

  const record = new MutationRecord();

• happy-dom/packages/happy-dom/src/nodes/character-data/CharacterData.ts

  Line 63 in be38195

  const record = new MutationRecord();

So for example if observer receives a callback about an attribute change, this is what you get:

    MutationRecord {
      type: 'attributes',
      target: null,
      addedNodes: [],
      removedNodes: [],
      previousSibling: null,
      nextSibling: null,
      attributeName: 'data-uuid',
      attributeNamespace: null,
      oldValue: null
    }

Here are docs for MutationRecord: https://developer.mozilla.org/en-US/docs/Web/API/MutationRecord

Thank you for reporting @sionzee! 🙂

I have added support for target in MutationRecord now.
