fix: Problems caused by image display ratio

[JWWTSL]

Log: Handled the problem that when the height/width of the image is too small, the actual size of the display style is incorrect and the interface problem when the image is displayed in the original scale.

Hi @JWWTSL. Thanks for your PR.

I'm waiting for a linuxdeepin member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
