[TW5] Broken code block word wrapping in transcluded tiddler with vertical tabs.

[Jeff Vance]

By chance, I found a specific scenario that seems to break word-wrapping when transcluding tiddlers into tabs.  I wonder if this is a TW bug. It specifically happens with a code-block that contains long dashed lines.   It's very easy to recreate with the following:

1. Create a tiddler with a single code block like this:

```

------------------------------------------------------------------------------------------

```

2. Transclude that tiddler into a tab (must be vertical)

<$macrocall $name="tabs"

  tabsList="[title[TEST TIDDLER]]"

  state="$:/state/test"

  class="tc-vertical"

/>

Then select the tab, and shrink the browser width. The transcluded version does not word-wrap, but the original tiddler does!  Also, I noticed it only happens if the it is using class="tc-vertical".  When reverting to horizontal tabs, the word-wrap works!

It's not a huge deal since it's a fairly rare scenario, but I thought I should point it out. Maybe it's something someone would want to fix.
