iOS 8 Bluetooth Keyboard: Safari issues

Is anyone else having this problem?

In Mobile Safari (iOS 8) it is no longer possible to mark a word or a sentence with a connected bluetooth keyboard. In textfields the cursor simply jumps from word to word but does not mark it. So no copying or deleting of text passages is possible with the bluetooth keyboard. I tested this with iPhone 6 Plus, iPad Air and the Apple Wireless Keyboard and several web sites, including this forum. Only CMD+A to mark everything works. In iOS 6 and 7 this was no problem.

This is a rather annoying issue since editing text in Wordpress or any other web-based form fields now requires using the touchscreen.
