[QA] webUISharingInternalUsersSharingIndicator/shareWithUsers.feature:154 failing randomly

[LukasHirt]

Another randomly failing scenario. Example https://drone.owncloud.com/owncloud/web/18187/28/14

@phil-davis After investigating it was found the problem with stale DOM reference.

So, what can we do? Refresh page after uploading file? or any other way?

@sakshamgurung stale reference does usually mean that the DOM changed and the test is trying to access to old DOM element, so we need to understand why that is happening. Why aren't we using the current DOM?

Just had a debugging session on another CI issue (in #5725) with @kulmann and we saw a stale element reference also, but it turned out it wasn't the actual reason for failure. Maybe that is the case here also?

I can confirm that the cause of the failure for this scenario is stale element reference. This might occur due to DOM refresh.
For this particular case, I suspect, file preview is causing the DOM refresh.
I duplicated the scenario multiple times and tried adding @disablePreviews to the feature file, all the tests passed.

For shareIndicator test step, the function that gets share-indicator will get retried once if the share-indicator is not found for the first time. If that happens then you are likely to see stale element reference error but the test will pass (if the retry passes).

this seems to be the case, according to @fschade the whole row is re-rendered when the preview is loaded

hopefully fixed in #5852
