Steps to reproduce:
- Mark the sentence "It was 113 feet 7 inches (34.62 m) tall and weighed over 9,000,000 pounds (4,080,000 kg).[1]" and cut it (Strg+X).
- Paste it in again (Strg+V).
- Click before "It" to place the cursor at the beginning of the sentence.
Result: The editor starts adding copies of the sentence in an endless loop, with the templates (see below) replaced by snowmen:
"It was ☃☃ tall and weighed over ☃☃.☃☃It was ☃☃ tall and weighed over ☃☃.☃☃It was ☃☃ tall and weighed over ☃☃.☃☃It was ☃☃ tall and weighed over ☃☃.☃☃It was ☃☃ tall and weighed over ☃☃.☃☃It was ..."
(Actually, if one scrolls or clicks somewhere in the page, the loop may stop, but I've observed it going on for more than a minute, generating 378 copies of the sentence.)
Here is the wikitext source of the sentence:
"It was {{convert|113|ft|7|in|m}} tall and weighed over {{convert|9000000|lb|kg|-4}}.<ref>{{cite web|url=http://www.sundayriveron-line.com/AngusSnowman_1.htm|title=Angus, King of the Mountain — World's Largest Snowman|date=February 19, 1999|publisher=Sunday River On-Line|archiveurl=http://web.archive.org/web/20071012082219/http://www.sundayriveron-line.com/AngusSnowman_1.htm|archivedate=2007-10-12}}</ref>"
