[WIN / EDGE] issue when compiling code on some pages of play.kotlinlang.org

[pmariac]

Just checking play with edge browser, found some errors when trying to run examples 2 & 3 on this page https://play.kotlinlang.org/byExample/05_stdlib/05_existential

I get these errors on MS EDGE :

the first 2 request are when running the first block of code the 2 next when running the second block the 2 last when running the 3rd block

Encounter problems of same type on others pages as well ie. https://play.kotlinlang.org/byExample/05_stdlib/07_firstlast
