Clarification on why <button> tag is among blacklistedtags list in diffservice.js for showing version difference

Hi,

I am looking into page html version diff functionality of aem and in that all tags except <button> tag's difference was not getting highlighted. I debugged that the diffservice.js which is responsible for this functionality has an array of blacklistedtags among which button is one. For my use case I overlayed the js and removed 'button' from the list and it works fine. I am curious to know why it was added there in the first place and if any impact will happen due to my removal of it.

Thanks in advance!
