plasma 5.11.2 on Arch.
The same tooltip has correct width when I move the cursor from right to left instead. My gif shows the issue.
it affects plasma 5.12 beta on Arch Linux.
There seems to be something funky going on when a tooltip does not have a sub text. I can also reproduce when moving from Printer (which has "queue empty" subtext) to device notifier which just says "no devices"

[Default Tooltip] Fix sizing
Unset the Label's default height which completely confuses the renderer either shifting the item vertically (e.g. when toggling
system tray popup), or letting it get too wide (e.g. when moving from a two-line tooltip to a one-line tooltip).
Also let the Layouts figure out sizing rather than trying to overrule it with flaky values.
