SUMMARY
***
Tooltips are not appearing in Dolphin
***


STEPS TO REPRODUCE
1. Open Dolphin
2. Hover over the toolbar (the one below title bar) buttons and see how the tooltips are appearing with explanations of what those buttons do
3. Make the left and right panel width narrow enough by dragging the vertical separator to the left until those locations are truncated (showing ... at then end of the names) and the right edge until the content (folder and files) names are trucated

ADDITIONAL STEPS
1. Open another program, for example Kate, so that the new program is focused, but Dolphin still visible
2. Open Dolphin's configuration window

OBSERVED RESULT
The title bar and toolbar tooltips seem  to show up as expected
In the left and right panel, there are no tooltips, even if the names are truncated and you need to see their full names
With the additional step 1 of having Kate open too and focused, hovering on Dolphin toolbar icons shows them highlighted with the blue edges, but the tooltips don't appear anymore
With the additional step 2 of viewing Dolphin's configuration window, many options don't have tooltips with explanations.
For example in General -> Behavior Show selection marker"

EXPECTED RESULT
Show tooltitps everywhere, especially when folder and file names are truncated, even if the "Show tooltips" option is not enabled in the configuration window
With another program opened and focused, like Kate, I still want to see the tooltips while I hover over stuff in Dolphin
For example in this case I was writing in Kate a list of bugs to report later and at this step I had just to hover on Dolphin without having to click anything.
And the same with working with side by side windows, I want to see the tooltips on the non-fucused window too.
Currently in side by side view it's working on the non-focused windows only on title bar buttons and content if the "Show tooltips" is enabled, but not on the toolbar or for the items that are truncated.

Show tooltips in Dolphin's configuration window, at least for some option that are not so easy to understand like ""Show selection marker"
