Good catch. The styles to separate the filename and close button need to be in a stylesheet (not inline).

@kidwm Could you move the in line styles to a style sheet? We could then go ahead and merge this change.

[kidwm]

@nethip I've done it.

[nethip]

@kidwm Thanks! I would do a quick round of testing and merge this.

@nethip @kidwm What is the status of this?

[ficristo]

LGTM, ideally the filename could be near the X to match other QuickEdit.
But at least now it works again.

@kidwm thank you.
