Continually changing file cannot be closed
If one opens a file (any plaintext file) that is continually modified in the background by an external program, such as a logfile, Mousepad immediately brings up the "The document has been externally modified. Do you want to reload it from disk? (cancel / reload)" dialog box, that (at least on xfce) is enforced into focus, and makes rest of the window impossible to be interacted with. As the file is constantly modified, the dialog box reappears instantly after closing it, which makes it impossible to close the tab where the file is.
I managed to close the tab by aligning the dialog box's top corner with the tab's closing symbol, and double clicking in rapid succession.
I think this is not a corner case, or trivial issue, since as mentioned above, intensely updated logfiles will behave like this, and Mousepad is very much one of the tools used for inspecting such files.
Reproduction: 1: Compose a simple python script that on a rapid loop (~0.05s cycletime) opens a textfile, appends something into it, and flushes the file onto disk. 2: Open said file in Mousepad
