Unable to click and drag in webview

I'm unable to select a large paragraph of text or drag sliding elements inside a webview. Is there a known limitation or is there something I can do to fix this?

what kind of webview, version of BTT & version of macOS?

The issue occurs regardless of whether it's 'Floating Webview / HTML menu' or 'Web View / HTML item' in a floating menu, and whichever URL I load (without any scripts added).
