When iterating over globs containing expansions, you can still quote all expansions in the path to better handle whitespace and special characters.
Just make sure glob characters are outside quotes. "${dir}/*.txt" will not glob expand, but "${dir}"/*.txt or "${dir}"/*."${ext}" will.
"${dir}/*.txt"
"${dir}"/*."${ext}"
Exceptions similar to SC2086 apply. If the variable is expected to contain globs, such as if dir="tmp/**" in the example, you can ignore this message.
dir="tmp/**"
