Issue Summary

When a user in Chrome or Edge tries to edit a multi-select custom field, ex: the Component/s system field or a Select List (multiple choices) custom field, when there are 10k+ options, there is a significant lag (30s+) in the results being displayed. This is with the multiselect.frother.renderer dark feature enabled. This behavior does not occur in Firefox, and the options for the field are rendered almost immediately. When tested in Safari, the options were rendered a couple seconds slower than in Firefox, but still significantly faster than in Chrome.

Chrome: Version 141.0.7390.123 (Official Build) (arm64)
Microsoft Edge: Version 142.0.3595.53 
Firefox: Version 141.0.3 (aarch64)
Safari: Version 18.5 (20621.2.5.11.8)

Steps to Reproduce

1. Create 10k+ options for the Component/s of a project or a Select List (multiple choices).
2. Enable the multiselect.frother.renderer dark feature.
3. Create a new issue in the project.
4. Edit either of the fields and start typing to get an autofill suggestion list of values.

Expected Results

The components (or other multi-select) custom field data should render in less than a couple of seconds ; like with the Firefox browser

Actual Results

The components (or other multi-select) custom field data renders in 30-50 seconds in Chrome and Edge.

Workaround

1. Use a different browser; ex: Firefox or Safari
2. Disable the multiselect.frother.renderer dark feature
