Fixed Preview editor button can be inadvertently triggered when scrolling on mobile

Affected version
XF 2.2


Well-known member
In XF2.2, scrolling through a thread can inadvertently trigger the reply preview action, if the initial screen interaction starts on the preview button. If no message has been entered yet, this triggers a 'Please enter a valid message' error in an overlay. In this scenario previewing is not my intention, so the error message comes as a surprise.

To reproduce: Try operating your phone 'one handed' and scroll with your right thumb. If your thumb touches the preview button as your start scrolling, you'll trigger the preview button.

Browser: Samsung Internet Browser 12 (Chrome 79)
OS: Android 9

As an aside, is there any point in activating the preview button when the editor does not contain any characters?
