Find / Replace All HTML files messes up coding and layout

[GoogleCodeExporter]

Please read http://code.google.com/p/sigil/wiki/ReportingIssues for
information about submitting a good bug report.

What steps will reproduce the problem?
1. I want to change <blockquote> to <div class="note"> in the entire book
2. If I click replace all -- the computer will automatically create the closing 
tag </div> but moves them all to the end of the page so I have about 30 closing 
div tags at the end and messes up the layout.
3. If I find / replace per page and one at a time, then it seems to work fine.

I do not have HTML tidy or Checking for errors selected.
...

What is the expected output? What do you see instead?

Bookwise replace without moving closing tags to the end. 

What version of the product are you using? On what operating system?

Sigil 5.2

Mac OS 10.7.2

Sigil require all but the currently opening document to be valid xhtml. In this 
case you are producing an invalid document which Sigil will try to fix.

The open document is valid as well.  I created the blockquote using SIGIL, then 
decided to use the div class instead. I was able to make the correction, but I 
had to find the item one at a time and change -- I could not replace all on the 
page otherwise it would put the string of div tags at the end.
