Using registered version of 5 (build 5025).

Replicate issue (this is what I did):

1. Go to Tools... Settings...
   
2. Go to Editor section --> Reserved Words
   
3. Change Language to HTML
   
4. Under predefined functions and tags: scrolled down to strong
   
5. Click the Edit Button
   
6. Place a checkmark next to Auto close
   
7. I also chose To Lower in the Change case: section, but this doesnt seem to affect the bug
   
8. Click the OK button
   
9. Click the OK button
   
10. In your HTML file (or php file where you have switched back to html), type in <stron
    
11. From the code completion list, choose <>strong
    
12. Add your trailing > character
    

at this point, the IDE should automatically close the <strong> element with </strong>, but it doesnt. bug? or am I missing something?

I think it figured it out. It seems the IDE has problems with nested elements when they are next to each other. For example, if I have

The IDE doesnt autoclose the <strong>, I guess, because it is inbetween/next to the closing </li>. It's doing the same thing for the <em> element. Actually, now that I look closer, it wont autoclose any elements that are embedded inside another if they are currently touching. So if you begin a <ul> and the IDE autocloses it, and then immediately begin a <li> it wont autoclose the <li>.

I would say this is definitely a bug.
