	Hi!, I am wondering about a HTML thing: if I create a <form> that contains an <input type="text"> and I read that input's pattern property, I get back the empty string. The input does not have validation associated to it: if I type the letter "a", the input does not become invalid. However, if I set that input's pattern property to the empty string, then the input has validation associated to it. If I then type the letter "a", that input becomes invalid (because "a" does not match the empty string pattern).
	Here is an example of what I am observing: https://jsfiddle.net/Lcur56ne/ . To reproduce, type "a" in the input (it does not become invalid), then press the button (the input becomes invalid). The console shows that input's pattern attribute type and value prior to setting it to the empty string.
	How can I make sense of that? In particular, how can I differentiate whether that input's pattern property is set to the empty string or undefined as in has not been set yet?
