Tooltip buttons are overlapping and thus hiding the text

the tooltip buttons i.e. the UP and the CLOSE button in tooltip are overlapping the text and making some text unreadable
for example: try pd.DataFrame() and Shift Tab inside the parenthesis
possible solution: reduce the opaqueness of the buttons

Reproduce the issue with pd.DataFrame() and Shift-Tab inside the parentheses, then locate the tooltip implementation and its button styling. The work is done when the UP and CLOSE buttons no longer obscure tooltip text; the payload does not name a file or test to run.
