/* Issue
|
|
For some native attrs you can unset only to set empty string.
|
|
This can be confusing as it is seen in inspector `<… id=""`.
|
|
Options:
|
|
1. Leave it, as it is native behaviour
|
|
2. Sets as empty string and removes the corresponding attribute when also has empty string
|
|
3. (*) Sets as undefined and removes the corresponding attribute when "undefined" string discovered
|
|
4. Point 2. with checks for coincidence (e.g. use special string)
