Unstable result, indentation changes on every run

Prettier 3.6.2
Playground link

--parser markdown
--tab-width 4

Input:

- Foo
  <!-- prettier-ignore -->
                                                    {{ image("../media/foo.png", "Foo") }}

Output:

- Foo
    <!-- prettier-ignore -->
                                                      {{ image("../media/foo.png", "Foo") }}

Expected output:

something stable that does not change on each run

Why?

REAMDE.md is a minimalized example of some mkdocs-based documentation. I would be fine with the code not being pretty, but at least it should be the same every run.

The playground above is not accurate; an unstable result can be produced locally like this:

README.md

- Foo
  <!-- prettier-ignore -->
                                                    {{ image("../media/foo.png", "Foo") }}

.prettierrc.yml

overrides:
  - files: "README.md"
    options:
      tabWidth: 4
      useTabs: false

Running with 3.6.2:

Fix this issue

Fixed on main, probably by these two PRs.

Fix indentation drift for indented code blocks in list items #19990 — don't re-indent indented code blocks in list items. My {{ image(...) }} line is parsed as an indented code block:
```
if (node.type === "code" && node.isIndented) {
  return print();
}
```
Fix HTML block indentation drift in markdown list items #19987 — don't re-indent HTML blocks in list items. That's the  comment itself:
```
- if (isFirst && node.type !== "list") {
+ if ((isFirst && node.type !== "list") || node.type === "html") {
```
