[Bug] Markdown: 3 or more images without a line break in a row do not get parsed correctly

### Bug Description

When there are n (n>2) images in a row and there is no line in between them, only the first image is being shown. This is related to the commit #1012 , which solves the issue of an image following a paragraph without an empty line, but it does not solve the issue of multiple images in a row.

### How to Reproduce

Try this markdown and use `markdownToDocument()`.

```markdown
## Case 1: Images on separate lines, no blank lines between

Only the **first image** renders below:


✅ If we add blank lines between them, all images render:




---

## Case 2: All images in the same line (inline)

Only the **first image** renders:

  
```

### Expected Behavior

One expects that all images load in any case.

### Operating System
