Once the experimental algorithm is on par with the smart diffing algorithm, we should deprecate the smart diffing algorithm and also use the experimental one in the side by side diff view (and also rename it).

Blockers:

• Check worst-case performance
• Ignore Whitespace Option
• Consider timeout
• Don't split up words too much

Advantages:

• Stable diffing algorithm, clean code
• Insertion optimizations
• Better scoring due to dynamic programming algorithm in some cases

Would:

• Fix Consider indentation level when shifting changes down and up #164574
