Flow editor becomes almost completely unresponsive after testing action to get webpage HTML bug:

Describe the bug

It seems that requesting somewhat large text, even when not that significant in size (1-2MB), causes the editor to become impossible to use when you are testing a flow. I was working on a web scraping workflow to request an amazon product page, then went to develop an action to take a list of selectors and output them. However, it becomes difficult to work with the sample data because the whole application stops responding.

To reproduce

Add my flow i created below
Test up to the first action by inputting any amazon product page url
Try doing anything in the browser window

Expected behavior

I'd expect the web application to be robust to test data it has access to.
I don't get why having 1-2MB of text as test data should cause a 4-8 second pause of the entire application for each character I enter into the "Summary" field of an action

Screenshots

Browser information

No response

Application version

EE v1.285.2

Additional Context

Here is a chrome dev tools performance recording i started just before I entered a single character into the Summary field of the next action I was working on: https://drive.google.com/file/d/1WrZL2z-S52lMcNKX3Pb3Jhyreux6NYd6/view?usp=sharing

Here is my flow:
