[Bug] After load(), in some cases the Y position is determined incorrectly & sizes are not restored.

[IgorA100]

Subject of the issue

I save current layout and then load it. In some cases, elements are assigned the value gs-y="0" instead of the stored gs-y="3"
This is also confirmed at https://gridstackjs.com/demo/serialization.html

Your environment

• version of gridstack.js - 10.1.2
• which browser/OS - Windows 8.1. Chrome 109.0.5414.168

Steps to reproduce

Expected behavior

After load() element's Y position should always match the stored gs-y="3", not gs-y="0"

There is also a problem with the sizes of elements when Load()

the bug culd be in the demo itself (fail to load the saved data) or the lib, but a bug reguardless...

[IgorA100]

No, this is not an error reading saved data. This shows up in my development environment as well.
Initially I looked for the problem in my development environment, and only then I started checking on the demo page.
What lib are you talking about?

As far as I understand, the error depends on the arrangement of the elements. Yes, it does not always appear. But try for yourself to perform the actions that I filmed on video and you will be convinced of the mistake!

I'm having a similar problem too. When I set float: true, this problem disappears, but I do not want to use the float feature.

[adumesny]

@erdoganfurkann that is a good hint! likely repacking after each item instead of after all info are read in.

[erdoganfurkann]

I have a temporary solution that worked for me. I always initialize the grid stack with float: true option, then change float to false using gridstack's float() method. I call float(false) in the dragstart and resizestart event handlers, but I guess this can also be called in a callback function that runs after the DOM is loaded.

if someone wants to donate I could take a look but I'm really busy these days, else make a fix. thanks.

I'm seeing cases where .save() is missing values like h for individual widgets, which causes the entire page to freeze when you try to call .load()
