Link window pop up obscures typing field

After typing two left hand brackets to begin a link, the pop up window offering links to choose obscures the part of the screen where the active input is occurring so I cant see what I am typing… so unrecognized typographical errors occur and the list of links is not useful. I have tried multiple themes and the behavior is consistent. Interestingly, it does not occur on my ipad. Is this is a bug, or is there some action I can take to fix this behavior. Thanks.
