SUMMARY
"Find All" and "Replace All" do not consider the same set as "All"

STEPS TO REPRODUCE
1. insert  the string '10, 11, 66, 101, 102, 103, 105, 106, 107, 108, 110, 111, 112, 113, 114, 117, 118, 119, 121, 124, 125, 126, 131, 132, 135, 136, 137, 157, 158, 159, 160, 161, 162, 163, 164, 180, 222, 223, 224, 225, 227, 230, 233, 237, 239, 242, 243, 244, 246, 248, 259, 262, 275, 276, 277, 278, 283, 284, 285, 292, 294, 296, 298, 300, 301, 302, 305, 306, 307, 308, 313, 318, 319, 320, 325, 406, 407, 408, 410, 411, 415, 417, 419, 420, 421, 425, 426, 428, 429, 430, 431, 434, 435, 440, 441, 442, 443, 445, 446'
2. select between10 and 11 the string ", " and hit CTRL+R, insert the string "', '" as replacement (without the double quotes obviously!)
3. select "Plain Text"
4. hit "Find All"
5. literally every occurence is highlighted (note this!)
6. now hit "Replace All"
7. replacement stops halfway through between 308 and 313, no occurence after 313 is replaced, despite "Find All" still highlights those as being exactly the same

OBSERVED RESULT
"Replace All" does not replace all occurences "Find All" finds

EXPECTED RESULT
"Replace All" does replace all occurences "Find All" finds
