Hi,
I am able to reproduce the issue at the demo site:
1) Open 'Find and Replace' dialog.
2) Click on the HTML tab.
3) Enter a word that needs to be found.
4) Click on the 'Find' button.
When the 'Find' button is clicked, the word does not get highlighted. It only highlights the word when I close the 'Find and Replace' dialog.
Thank you.
