hy,
i see this issue when working in chrome and firefox on mac (latest versions). i use the tab-widget with a few tabs. when i start dragging one tab to another position but then release it to early, so that it jumps back to the original position, the content of this tab is lost.
this happens pretty often as sometimes when you click on it, it makes a small movement...

i have also seen it in various pages where we use elementor with different configuration of other themes/plugins/...

hope you can reproduce and fix it :)
matt
