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!
