Dashboard Input Control multi-select options do not work when browser is at certain middle sizes

Kibana version:
Originally reported for 7.8.0 by a customer.
Reproduced in master

Elasticsearch version:
Originally reported for 7.8.0
Reproduced in master

Server OS version:
Mac Catalina 10.15.6

Browser:
Chrome Version 84.0.4147.135 (Official Build) (64-bit)

Original install method (e.g. download page, yum, from source, etc.):
Reproduced running from source

Describe the bug:
At certain browser sizes, the multi-select inputs clear when selected items span over multiple lines
Steps to reproduce:

1. Run kibana
2. Install the sample flight data set
3. Resize the browser such that more than one input is next to another.
4. Open the dashboard and select enough Origin Cities so that the number selected spans over multiple lines.
5. Observe that once the number of items selected spans over more than one line, the input clears.

** Work-around**
I figured out how to work around the issue by resizing the Input Control panel such that there is only one input per line in the panel.
With one input per line, one can select items such that they span multiple lines.
Expected behavior:
The selected items should remain

Screenshots (if relevant):
Inputs clear in this case:

Inputs don't clear in when there is only one per line in the control vis:

Errors in browser console (if relevant):
None
Provide logs and/or server output (if relevant):
None

Hey everyone! I believe this is a duplicate of #76142, and has been fixed in #76573.

You should get that fix in 7.9.2
