I'm not sure it can be avoided. I suppose the input bar is not actually part of the skin.
There is a possible workaround by using !Z-Pos as part of the !Execute that calls the input, and then as part of the Input Command but if someone escapes out of the input, no command will be ran and Z-Pos can't be changed back to Always on top.
BTW, it could be useful if the input measure could include some Command0 that's ran when esc is used to cancel the input. It could be left empty or omitted for ne command like now but if some bang changed the skin when calling for the input, this would allow to revert the skin to it's previous state.
Not sure how hard it would be to code this.
