这个隐式 div 关闭是否与 HTML 规范相矛盾？

Question

In the following HTML code, my browser appears to be implicitly closing the div tag, such that cell one appears blue, but cell two does not.

<table>
<td><div style="background:blue">cell one</td>
<td>cell two</td>
</div>
</table>

Intuitively, this seems like sensible behaviour, but it appears to contradict the HTML spec.

From 12.2.9.6 Unclosed formatting elements

nested formatting elements (such as b) get collected and continue to be applied even as the elements they are contained in are closed

From 4.4.15 The div element

Neither tag is omissible

My reading of this is that the opening of a new td tag shouldn't implicitly close the div tag, and therefore the styling should continue throughout the table.

Is there something in the spec that I've missed that makes the browsers' behaviour consistent with the spec or is the browser going outside of the formal spec?

Tested with Chrome, Firefox, IE, Edge

No because:

A div is not a formatting element

The following HTML elements are those that end up in the list of active formatting elements: a, b, big, code, em, font, i, nobr, s, small, strike, strong, tt, and u.

Tables are special

See 12.2.6.4.15 The "in cell" insertion mode which says:

Generate implied end tags.
