Release:

Service Pack(s):
3900.102.0, 3900.104.0, 3900.106.0
Description:

When using the symbols < and > in LaTex inside a function they are replaced with the HTML entities "&lt;" and "&gt;" once the text editor is refreshed. This causes the function to be rendered incorrectly.

Steps to Repeat:
  1. Log into Blackboard Learn Ultra Experience as an administrator 
  2. Access an Ultra Course
  3. Create a test
  4. Click on the (+) icon to add content > Add Text
  5. Copy and paste the following LaTex function: $$f(x) = \left\{\begin{array}{cc} x+1 & \textrm{ if } x < 0 \\ -x^2 & \textrm{ if } x > 2\end{array} \right.$$
  6. Save changes
  7. Notice how the function looks like once rendered
  8. Refresh the page, or close out the test window and access the same test again
 
Observed Behavior: 
They are replaced with the following HTML tags "&lt;" and "&gt;
 
Expected Behavior: 
The < and > symbols are displayed normally. 
 
 



Resolution/Workaround:

  1. Open ⊕ > ∫(x) Math
  2. paste the LaTeX here
  3. If that doesn't work, re-open the Math window and press ctrl+shift+L. A second simpler popup appears. Paste in this window.
