DropDownButton displays the separator for down arrow with incorrect height on macOS.

Let's make sure issue is not already fixed in latest builds first.

• I verified I can reproduce this issue against latest Integration Build of Eclipse SDK

Steps to reproduce

From a fresh installation and clean workspace:

• On MacOS, open eclipse marketplace, click "installed" tab:

• On Windows side it is fine:

I expected: The dropdown button should be identical across different OS

But got: MacOS has a broken dropdown button.

Tested under this environment:

• OS & version: Mac, Windows
• Eclipse IDE/Platform version (as shown in Help > About): all versions with marketplace.

• I understand reporting an issue to this OSS project does not mandate anyone to fix it. Other contributors may consider the issue, or not, at their own convenience. The most efficient way to get it fixed is that I fix it myself and contribute it back as a good quality patch to the project.
