Harper presumably does not recognize HTML newlines as spaces in certain lints

**What got flagged?**
```html

People who encounter this form of fate are sent to
purgatory, forced to dwell on old debts and mistakes
forever.

```
Harper error:
`Use 'too' here to mean ‘also’ or an excessive degree. (Harper ToTwoToo)`
(in relation to '...sent to / purgatory')

**Why is this incorrect?**
Harper lints should recognize when HTML line breaks are replaced by spaces (e.g. whenever text isn't wrapped in a `

` tag

Reproduce the Harper ToTwoToo warning with the provided HTML snippet, then inspect the HTML linting and whitespace-handling entry points. The fix is done when line breaks in ordinary HTML text are treated as spaces, while text inside

 remains unchanged and the reported lint is no longer triggered incorrectly.
