Help in element-UI dialog pop-up box vue-froala-editor rich text editor, edit picture toolbar does not display

I use element-ui "s dialog pop-up box, showing rich text in the pop-up box, and uploading pictures can be successful, but when you click on the picture, there is no toolbar for editing the picture. Put the rich text outside (not with the pop-up box but directly) and click on the uploaded picture. The picture editing toolbar displays normally!
could you tell me why this is?

my menu / clicked column did not respond. Finally, I saw css because its z-index is small. I changed it to a little larger than the current window to display normally.
I used a tinymce rich text editor
to add

to css in App.vue.
.tox-silver-sink{
        z-index: 2008;
    }
