[Lens] overflowing search phrase in the combobox of fields problem

[mbondyra]

Describe the feature:
When search phrase in the combobox of fields overflows the width of the container, we only show characters starting from the beginning of the string. That forces a user to guess the remaining characters.

Quoting @dej611 from:
##106285 (review)

Probably the only enhancement would be to have some a better handling of the highlight when all the text visible is already selected.

Say you have a list of long fields (these are from metricbeat-*), once you type enough to fill up with the Highlight component all the visible space, there's no much you can do to differentiate all these fields:

Reaching that point you start either go to the field you know already, or guess type chars to get the one field you are looking for (for instance: is it .remove or delete? is it .deletecompare or deleteorcompare etc...).
It would be nice if the highlight behaviour was more right-aligned showing always at least non-highlighted letter so that you can better guess.

Proposed solution: display extra 3 characters from the right side for example (based on the example above):
...spike.namespace.client.del...

This is fair, we should check the average field names (from our integrations dashboards for example) and then decide a strategy

This has been resolved in recent kibana versions
