Does the tooltip flicker in and out as you move your mouse, like in MCPE-10512?

I can't update the affected versions, but this is confirmed for 14w32b.
Unsurprisingly, this carries on to 13w38c.

As far as I'm concerned, this is not related to MC-9807. As you can see from my screenshot, there is a lava lake nearby, and there's light behind my character. However, the light behind my character is from where I dug down and broke through, and the lava lake is too far away. The light level (bl and sl) on the dirt blocks containing grass is 0.
Light level aside, this should be considered unintended, even for MC-9807. Tall Grass and Double Tall Grass should only be generated on top of grass blocks, not dirt blocks.
I think what's happening is that it's getting the effect right, but consuming the first book in your inventory, which may not be the one you used.
