Inline quotion style problematic

[garry.yao]

Sometimes inline style should own priority, style with higher priority should be applied at a more high level. Here's a concrete example

Reproducing Procedures

1. Open the 'replace by class' sample page;
2. Load the following content with selection:

   <p>
   	<strong>[some</strong>test<strong>text]</strong></p>
   

3. Apple 'Line Quatation" from 'Format' combo;
   • Actual Result:

     <p>
     	<strong>so<q>me</q></strong><q>test</q><strong><q>te</q>xt</strong></p>
     

   • Expected Result: The quatatoin style doesn't break into pieces

     <p>
     	<strong>so</strong><q><strong>me</strong>test<strong>te</strong></q><strong>xt</strong></p>

Similar with #3599.

The "intact" name doesn't look like intuitive for this property in the style definition. We must think about something better.

This patch needs to be updated. Additionally, instead of "intact", let's call the property "maximize" or "avoidBreak", or anything that makes it more meaningful.
