Problem with foreignObject in SVG pattern

I try to use foreignObject in pattern, but it doesn't work. Is the problem in me or in code?

Specification

Image in pattern: work 

<pattern id="pattern-image">
    <image ... />
</pattern>

Text in pattern: work 

<pattern id="pattern-image">
    <text ... />
</pattern>

ForeignObject in pattern: fail? 

<pattern id="pattern-image">
    <foreignObject ... />
</pattern>
