JIRA has different behaviour for how it renders custom field descriptions and options depending on if it's running BTF or on OnDemand.

• On OnDemand, custom field descriptions are wiki markup, but on BTF they're HTML.
• On OnDemand, custom field options (e.g. for checkbox) are plain text, but on BTF they're HTML.

I propose we make BTF behave the same as OnDemand. The rational is:

• The differing behaviour introduces development and support costs, and makes it more difficult for users transitioning BTF ⇿ OnDemand.
• Supporting HTML enables XSS attacks.
• Supporting HTML for options causes problems for other features, e.g. charts (see attachment)
