[Discover] Search and time disappear from screen when editing the hour of the Absolute Start date

[blontrock]

Kibana version: 7.9.0

Elasticsearch version: 7.9.0

Server OS version: CentOS 8

Browser version: Firefox and Google Chrome

Browser OS version: Windows 10

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

Describe the bug: The search box and time selection box disappears when editing the hour part of the Start date in the Absolute date selection box. It seems to break for specific changes, not everything.

Steps to reproduce:

1. Go to discover in Kibana.
2. Click on 'last 15 minutes'
3. Click on Absolute
4. Click on the hour of the 'Start date'
5. Select the 2 digits of the hour and then type '0'.
6. The whole search box and time selection disappears.

Expected behavior: The search box and time selection is still there and I can finish the hour part.

I can't reproduce, this should not be Discover related, dear @blontrock, could you try if the same error is reproducible in Dashboard? thx

[blontrock]

It also occurs in the dashboard. When I select the hour part (11) and type a 0, the whole search box and the date is immediately gone. It comes back when reloading the page.

[kertal]

thx! I could reproduce it, also in visualize, but I've to select a day before I try to edit the time string:

In visualize also the visualization isn't displayed, can't reproduce in master, so it seems to be a 7.9.x issue

I can confirm similar behavior in kibana v 7.9.1 and v 7.9.0. In the below gif I select the date and hit backspace to try and change the time.

Tracked down to this elastic/eui#3750 fix. This is why not reproduced in master (using newer eui with a fix for this).
Should land in Kibana with 7.10 release.

verified this behavior on 7.9.3 BC1 - I could not reproduce the issue - all good with the timepicker in discover.
correct error message is seen Expected format MMM D, YYYY @ HH:mm:ss.SSS
