Any additional comments?

This problem came up today while developing on my company’s Vue powered web apps. One colleague can reproduce this issue while another one can’t. I could not find this issue reported yet, hence me creating it now.

Does anyone else have this issue?

For now I need to uninstall Vue Devtools from Chrome and use Firefox instead to debug my Vue apps, because over there it works as expected.
