Bug Description

What happened?

When I create many environment variables, then typing in any input field (url, query parameters, etc.) becomes unusably slow, taking many seconds between each typed character. Switching between a near empty environment, and an environment with many variables will switch between fast typing response and slow response respectively. I'm not sure how many environment variables are necessary to reproduce, but I have well over 100+.

I expect typing to be quick even with many environment variables.

Steps to reproduce

Create multiple environments
Create 100+ environment variables in 1 of the environments.
Select the environment with many variables.
Reference one of the variables in any field of the tab (url, query parameter, etc.) using <<somvar>> syntax
Typing will become slow and slows down over time with more use.
Switch environment to a new or nearly empty environment and typing speeds up.

Deployment Type

Self-hosted (on-prem deployment)

Version

2025.9.2
