Websites wont recognize the letter "ö" as an input unless held down to type multiple

Description of the issue:
The letter “ö” from the swedish alphabet won’t recognize as an input unless held down to type multiple in a row. Other characters such as “å” or “ä” will type just fine. “ö” is recognized as an input when typed in the address/seach bar but not when typing inside a website, including this one.
