[TSVB] Table sorting broken

[majagrubic]

Kibana version: master

Elasticsearch version:

Server OS version:

Browser version: Chrome

Browser OS version: Mac OS

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

Describe the bug:
When trying to sort on one of the aggregated fields in a TSVB table, sorting is broken.

Steps to reproduce:

1. Open TSVB > Table

2. Select kibana_sample_data_logs as index pattern

3. Create the following table:
   

4. Click on bytes -> the results are not sorted

Expected behavior:
Bytes are sorted ascending and then with another click, descending.

Screenshots (if relevant):

Errors in browser console (if relevant):

Provide logs and/or server output (if relevant):

Any additional context:
I believe this is a regression introduced recently. I tested on 7.1.1. and it works as expected.
Tracing the code a bit, it seems that the uiState does not register new change and always returns _default_ as column:

kibana/src/legacy/core_plugins/vis_type_timeseries/public/components/vis_types/table/vis.js

Line 143 in 3a915b2

onUiState(stateKey, { column: item.id, order });

Possibly related: #51887

I am experiencing this as well on Elasticsearch / Kibana 7.5.0. Is there any update on this?

Is it possible to have this issue prioritized?

This issue, coupled with TSVB Table sorting in dashboards being broken (#49626), is putting the TSVB Table visualization in an unusable state.

Sorting is not working on Column in the data table.
Will also like to be able to sort by the 'filter-ratio' meteric.
