When displaying parsed tap results (URLs like
/jenkins/job/JOB_NAME/BUILD_NUMBER/tapResults/?) the extra YAML properties are not HTML escaped, which can causes display issues.

For example, my TAP file looks like:

ok 1
   ---
   actual: (#<ECHECK-DATA {10038520F3}>)
   ...
0..1

This is valid per the InstantTAP

The angle brackets in TAP are displayed directly into HTML, and the test message is not displayed. In my browser that gets rendered to HTML as

<td style="width: auto;">actual</td><td>(#<ECHECK-DATA {10038520F3}>)</td>

I would like it rendered as:

<td style="width: auto;">actual</td><td>(#&lt;ECHECK-DATA {10038520F3}&gt;)</td>
