Custom tag with angle brackets triggers an error

[Essay97]

Describe the bug

I added a !<import> custom tag to my yaml.customTags config:

But when I try to use it in a YAML file, i get an "unknown tag" error:

I noticed that if I add an !import custom tag instead of !<import> it just works.
Is there any kind of limitation with using angle brackets? I really can't remove them
