Breaking a double tall grass from the top part will not yield any seeds. Breaking the lower part or removing the block under the plant will.

Two-block grass is supposed to yield seeds? When did that happen? I hardly ever get seeds, whether breaking the top or bottom....
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.
Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been delivered.
Not sure if this is a bug or intentional but it has always been this way AFAIK since two-block tall grass and flowers were added.
Personally, I would like for the top half to also drop seeds. For consistency.
