What Happened?

When pasting larger images (e.g. 1200x600 pixels) in the base64 format (e.g. from websites) into Logseq, it freezes completely. The only way is to kill it and start again.
Smaller images (300x300) are not a problem. Waiting doesn't help.

Reproduce the Bug

1. Open any page in logseq
2. find an image with large dimensions (e.g. 1200x600)
3. convert it to base64, e.g. https://www.base64-image.de/ and copy it to the clipboard
4. Paste it into Logseq

Result: The app freezes and you cannot do anything besides killing the process. close button doesn't do anything.

Expected Behavior

The image is pasted and visible

Screenshots

No response

Desktop or Mobile Platform Information

Windows 10, Logseq 0.9.11

Additional Context

The images are in PNG, but base64 encoded. This happens if you copy some images from websites.
Workaround: Paste to any image editor, copy it again

Start by reproducing the freeze in the Logseq desktop app by copying a large base64-encoded PNG and pasting it into a page on Windows. Trace the clipboard and paste handling from that entry point, then verify that the image appears without freezing and that smaller-image pasting still works.
