Emoji at start of layer name with truncation causes noticeable performance drop

​

Steps to reproduce:

1. Any emoji at the start of layer name
2. Long layer name that causes truncation ellipsis (...)

• If emoji at start AND no truncation, performance remains stable.
• If no emoji at start AND truncation, performance remains stable.

Only when both emoji at start and truncation exists do you run into performance issues.  This only affects the active tab and doesn’t seem to spike up CPU, but when you have many of these layers it becomes unusable.

Solution for now is to remove the emoji at the start.
