When I tried validating a select tag with strict mode turned on, I noticed that validation does not work well when I select multiple options because it will reset all the selected options and leave just one selected.
I noticed that when you build a validation rule using the function addovcustomrules, and you use the custom rule with a required rule on an element, the script will not validate the required rule. But will validate your custom rule skipping the required rule
Using strict mode, when you provide a value that shouldn't be allowed, and it turns out that the value by default has already been defined by the library, the library returns the values even if they are duplicates
This happens when you try to validate an email input with 37 characters or more.
In Microsoft Edge, you can see the option to stop the long-running script, but in chrome, the page freezes and won't reload. But will reload after you must have reopened and closed the tab multiple times.
I noticed that form validations does not work without adding the Required validation rule first.
So if you have the validation rule; [ TEXT ] on an input element, the script will not check for this rule unless you attach a required rule to it. [ R, TEXT ]
