Tfs Work Item HtmlFieldControl height on sharepoint

During my investigation to create a customer friendly interface for Tfs Work Items, we've found an interesting 'hidden' feature: the Height attribute. Without it, the HtmlFieldControl take up a huuuuuuuuuge amount of space:

But by adding the super secret nowhere to be found Height attribute, magic happens...

*badadum*

<Tab Label="Issue Details">
  <Group>
    <Column PercentWidth="100">
      <Control FieldName="WhatWentWrong" Type="HtmlFieldControl" Label="What went wrong:" LabelPosition="Top" Height="75" />
    </Column>
  </Group>
  <Group>
    <Column PercentWidth="100">
      <Control FieldName="ReproduceSteps" Type="HtmlFieldControl" Label="Steps to reproduce the problem:" LabelPosition="Top" Height="75" />
    </Column>
  </Group>
  <Group>
    <Column PercentWidth="100">
      <Control FieldName="ExpectedBehavior" Type="HtmlFieldControl" Label="What is the expected behavior:" LabelPosition="Top" Height="75" />
    </Column>
  </Group>
</Tab>

By the way, to prevent the Html controls, make te type of the field PlainText.

Cheers!
