WebDriver is stuck without logs and fails on mocha timeout

[dmlemeshko]

While working on WebDriver migration we noticed strange failures in CI when WebDriver is stuck (no logs provided) and fails within time on reaching mocha timeout for suite/test.

Example:

[00:07:48]                 │ debg Find.findByCssSelector('[data-test-subj~="visualizationLoader"]') with timeout=10000
[00:07:48]                 │ debg Readed rendering count 8 8
[00:07:48]                 │ debg --- retry.try error: expected 8 to equal 9
[00:07:49]                 │ debg TestSubjects.find(visualizationLoader)
[00:07:49]                 │ debg Find.findByCssSelector('[data-test-subj~="visualizationLoader"]') with timeout=10000
[00:07:49]                 │ debg Readed rendering count 8 9
[00:07:49]                 │ debg Find.findByCssSelector('div.visAxis__splitAxes--y > div > svg > g.ValueAxis-1 > g:last-of-type.tick') with timeout=10000
[00:07:49]                 │ debg maxYLabel = 500, maxYLabelYPosition = 226.9673309326172
[00:07:49]                 │ debg Find.findByCssSelector('div.visAxis__column--y.visAxis__column--left  > div > div > svg:nth-child(2) > g > g:nth-child(1).tick') with timeout=10000
[00:07:49]                 │ debg Find.allByCssSelector('svg > g > g.series > rect[data-label="Count"]') with timeout=10000
[00:07:49]                 │ debg chartTypes count = 59
[00:10:55]                 └- ✖ fail: "visualize app  vertical bar chart should have `drop partial buckets` option"
[00:10:55]                 │      Error: Timeout of 300000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

Here WebDriver stuck on running following code:

      const chartData = await Promise.all(chartTypes.map(async chart => {
        const barHeight = await chart.getAttribute('height');
        return Math.round(barHeight * yAxisRatio);
      }));

Current guess is that WebDriver has issue when it is call in Array.map

List of failed tests:

• FailedJOB=x-pack-ciGroup2
  • X-Pack Functional Tests.test/functional/apps/logstash/pipeline_list·js.logstash pipeline list route select all checkbox toggles selection for all rows
• FailedJOB=kibana-ciGroup12

I am pretty sure the work done in #31446 fixed this. If not, reopen.
