I love bugs that are just confusing and/or break your mental model of how you think the software works.
Here is a good example: Given the following HTML in Gecko, what happens when a user clicks the button?
<form method="POST" action="/form-action"> <a href="/anchor-target"> <input type="button" value="harro"> </a> </form>
GET /anchor-target HTTP/1.1 GET /anchor-target HTTP/1.1
2 GET requests? Okay, perhaps some sort of event bubbling problem; it's relatively common in GUI internals. But what about:
<form method="POST" action="/form-action"> <a href="/anchor-target"> <input type="image" src="http://upload.wikimedia.org/wikipedia/en/7/75/LHC5.jpg"> </a> </form>
POST /form-action HTTP/1.1 GET /anchor-target HTTP/1.1 GET /anchor-target HTTP/1.1
Wait, this time it POSTs the form and makes 2 GET requests?
Answers in a Bugzilla report, thanks.

From the HTML spec:
`TYPE=IMAGE' implies `TYPE=SUBMIT' processing; that is, when a pixel is chosen, the form as a whole is submitted.
i.e. the POST request in the second case is not a bug. The only bug I can see here is the duplicated GET.

Looks like https://bugz... and https://bugz..., but wow, very weird.

If you s/button/submit/ in the first example, do you also get a POST and two GETs?
By the way, note that your example violates HTML5, at least: an "a" element cannot contain interactive content, which includes any input with type other than hidden.
