How to disable "No Default Proposals" in eclipse content assist for PHP?

Question

Is there a way to disable the message "No Default Proposals" at the content assist function in eclipse?

The content assist function is really great. However it's really annoying whenever eclipse does not find a matching insert and displays the following:

One has to click somewhere or hit a key to close it.

I'm using: eclipse Photon (4.8.0) for PHP on ubuntu.

Edit:

A solution is desired where the "auto activation" is enabled in eclipse properties! But: Whenever the "content assist" feature does not find a proposal it should not show an empty proposal popup window or close it as soon no more proposals are found. I think, I've seen this function in Zend Studio which is a proprietary fork of eclipse.

Yes, it's annoying. I'd like to meet the person who made the decision that popping up a blank box and requiring esc to be hit for everything was such a good idea.

Click Window/Preferences Expand your language (ie: php, Java, etc) Expand Editor, click Content Assist Toward the bottom right, un-tick Enable auto activation.
