number of library items not fully displayed -> show as tooltip

From jabref created by ghost: JabRef/jabref#10208

JabRef version

5.9 (latest release)

Operating system

Windows

Details on version and operating system

Windows 10 22H2

Checked with the latest development build

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

I have downloaded 2 databases in BibTeX format: one is an arcade game database (45974 items), the other a game console/computer database (134352)

Please look at screenshot. The number of items in the library is not fully displayed (see at the left). Only 4 digits are displayed, the rest in front of it is gone. Could it be fixed so I see the currect number of items? I know it are A LOT but it's possible to have such a big library :)

Attached are the 2 bib files
