Why is the table in my question not rendered correctly?

Question

I created this question and added the following table to it:

|| EUR | GBP |
|-| - | - |
| EUR | 1 | 0.85 |
| GBP | 1.17   | 1 |

In the preview it is shown correctly but why is it not rendered correctly in the actual question? Is it simply a bug or is my syntax wrong?

I fixed it for you.
You just need to add a blank line above the table.

Could be a bug or a small difference in how the content is interpreted in the preview and in the actual question
