Preserve single-line html inside embedded html (tagged template)

[isAdrisal]

Based on denoland/deno#30677 (and also mentioned in denoland/deno#30103)

dprint-plugin-typescript version: 0.95.12

The current behaviour means that single-line, whitespace-sensitive html (like the below spans) are formatted with surrounding whitespace where there shouldn't be any.

I separately tested the behaviour in markup_fmt directly, which (correctly) treats <span> elements as whitespace-sensitive and doesn't add surrounding whitespace, and so confirmed the whitespace was being added by this plugin.

Input Code

let htmlStringOne = html`<span>foo</span>`;
let htmlStringTwo = html`  <span>foo</span>`;
let htmlStringThree = html`
<span>foo</span>`;

Expected Output

let htmlStringOne = html`<span>foo</span>`;
let htmlStringTwo = html`<span>foo</span>`;
let htmlStringThree = html`
    <span>foo</span>
`;

Actual Output

let htmlStringOne = html`
  <span>foo</span>
`;
let htmlStringTwo = html`
  <span>foo</span>
`;
let htmlStringThree = html`
  <span>foo</span>
`;
