Issue with two successive tables

I noticed that the second table is not rendered to HTML when there's one new line between two successive tables. If I insert two linebreaks, it works. Is this intended?

This doesn't work:

```
| Name | Function |
|--------------|---------------------|
| Joe | Operations director |
| Tom | Project manager |

| Name | Function |
|--------------|---------------------|
| Joe | Operations director |
| Tom | Project manager |
```

This works (two new lines)

```
| Name | Function |
|--------------|---------------------|
| Joe | Operations director |
| Tom | Project manager |

| Name | Function |
|--------------|---------------------|
| Joe | Operations director |
| Tom | Project manager |
```

Reproduce the one-blank-line and two-blank-line table examples from the issue, then locate the table parser entry point or relevant tests in MultiMarkdown-6. Check how successive tables are separated and confirm the intended behavior before changing anything; done means both examples render the expected two HTML tables.
