Overlapped texts in tooltip when mousing over listed pets in AH

[Alinnia]

Running Software (issues missing this information will be deleted):

• Addon version: 8.3.8
• Server patch: 8.3.0 (34220)

Have you read the changelog? (please don't waste our time)
Yes, I've read it.

Describe the bug
When mousing over a listed pet in the Auction House, the Seller information overlaps with the Zone information as they appear on the same text line. For raid drop and vendor pets, the Seller and Time Left information overlaps with other lines of texts. The overlapped texts are unreadable.

To Reproduce
Steps to reproduce the behaviour:

1. Open the Auction House
2. Search for a pet in the Buy tab
3. Mouseover a listed pet
   or
4. Click on the Sell tab
5. Right click on a caged pet in your bag
6. Mouseover a listed pet

Expected behaviour
The texts not to be overlapped so that they're readable.

I have the same issue but not only in AH. It happens also in any caged pet tooltip in bags.

I'm seeing this issue as well.
The issue seems to be in tooltips.lua, but no matter what I do, I'm not able to fix this.

The text added by this addon is overlayed on top of the "Pets in this group may vary in stats, level, and quality" message.
