[2.0.0+] Dropdown scrolling effecting table scrolling

[tjgambs]

Description

Scrolling inside a dropdown effects both the dropdown and the table behind it. This should instead be only scrolling the dropdown.

Steps to reproduce

1. Open a dropdown with greater than 10 values
2. Scroll inside that dropdown
3. The scrolling effects both the dropdown as well as the table behind it.

Your environment

• Handsontable version: 6.2.2
• Browser Name and version: Chrome 73.0.3683.86, Firefox 62.0.2, Safari 12.0.3
• Operating System: MacOS 10.14.3

In terms of replicating this issue, all browsers on MacOS have the issue as shown in the gif above: Chrome, Firefox and Safari. I haven't had any problem with Google Chrome on Linux, but when I try to use Firefox on Linux, this scrolling issue appears again.

I did some searching through your old issues and I found this issue that appears to be similar to mine: #4651

Any help regarding the issue would be greatly appreciated. Thanks.

As a follow up on this issue, I have done some debugging and have found that the correct functionality exists on handsontable v1.18.1. After the update to v2.0.0, the scrolling issue begins to appear. I hope this helps.

Really appreciate @tjgambs

I can also add that it works fine on Windows 10, but breaks on Mac.
