Subject: [PATCH 020/119] refactor(shared-utils): Improve readability and
 consistency in code comments (#8529)

Improvements that apply to all comments:
- Consistent use of periods
- Consistent use of commas
- Consistent capitalization
- Correct use of articles (a, an, the)

Improvements to specific comments:
- Correct pluralization in the description for helper functions
- Reword for clarity and break into shorter sentences the description
for `polyfillBind` function
- Reword for clarity the description for `genStaticKeys` function
- Add a previously missing description for `looseIndexOf` function

Fixes: https://github.com/vuejs/vue/issues/8528

Subject: [PATCH 056/119] fix(transition): check existence of `el.parentNode`
 (#8422)

fix #8199

* fix(transition): check existence of `el.parentNode`

If the new parentNode gets a `textContent` or `innerHTML` property during
patching, the `transition` node would have been detached early, which means
`el.parentNode` no longer exists.

* fix(vdom): should not reuse nodes with `textContent` / `innerHTML` props

Subject: [PATCH 096/119] fix(core): avoid mutating original children when
 cloning vnode

The on-demand clone strategy introduced in 956756b mutates the owner
array of the cloned vnode. This causes the newly cloned vnode to be
destroyed when the parent node is destroyed. This is fixed by cloning
the children array when cloning a vnode.

fix #7975
