Settagdata bug?

Hello all,

The following code will delete <Test3=“Number3”>
vTest = |<Test1=“Number 1”>;<Test2="">;<Test3=“Number3”>;<Test4=“Last”>|
settagdata vTest, <Test2="|, |">|, TextEditingResult

It only happens when the tag has no value, “” if I put a space between quotes it works. <Test2=" ">
