Ipad os - how do I turn off links opening new windows?

Since updating to iPad os I keep getting links popping up in a new Safari window if I happen to linger on a link a bit too long, such as when scrolling a page slowly. It seems to happen more on linked images. The only way to close the window is to double click the home button and close the window from there.
Is there a setting to turn this behaviour off?
TIA
