This is a very fun bug!
Steps to reproduce:
- Go to https://tools.wmflabs.org/svgtranslate-test/File:Ear-anatomy-text-small-en.svg
- Wait a few seconds for the file to load.
- While initially the file loads correctly (red labels), the labels change color a second later -

Fix the issue and make sure it does not happen for any other files either.
