Double Block Hydration on browser resume (unconfirmed)

[raymondtri]

Description

This is a really isolated issue at the moment that I haven't been able to replicate (I can sometimes) so keep that in mind.

Essentially the working theory is that if you load an admin module editor page, and then navigate away from that page in a way that causes the active browser to suspend the memory for that tab (or something), when you come back to resume that browser tab, it causes a rehydration event or something which is causing blocks that were originally there to be duplicated.

Steps to reproduce

Add blocks to a module and save the entry (Key Features and Column Callout blocks in the image)
Come back to that module edit page at a later date
Add more blocks (product info slider, resource download, and product reviews in the image)
Navigate away for a while (30-45 minutes) to get some information
Come back to find original blocks had duplicated

Expected result

Blocks shouldn't duplicate

Actual result

Blocks did duplicate

Versions

Just had an update on this as it happened again when the pages were completely closed - not just suspended.

Will probably be pivoting into trying to see if there's a way for a double save event or something like that causing blocks to duplicate
