BAML playground seems have a bug. For instance,when I running a test(figure 1, index 2 box) and it not end,meanwhile I ran another test(figure 1, index 3 box). The previous test won't end.And its result will instanly show in index box 3.But when test 3 truly running,its shown data(result of test2) replaced by truly test3 result. https://cdn.discordapp.com/attachments/1119375594984050779/1461271580054126673/image.png?ex=6979c4b5&is=69787335&hm=a0bba73d1508ef95e951fc6202a46179d5771e00c03e245e69b015c6a672536a&
