Subject: [BUGFIX] Prevent bouncing fileupload field
X-Git-Tag: 3.0.0~4
X-Git-Url: https://git.p6c8.net/jirafeau_mojo42.git/commitdiff_plain/f2ec213d8b9b828c8f81b82349cc103328a5a2e5?ds=inline;hp=1a6ad62b5b5a5e40fb867e741a896268be39df98

[BUGFIX] Prevent bouncing fileupload field

After a file is selected in the first step of an upload,
the options are shown and the fileupload field is resized
to a much smaller field. In Chrome and other browsers
this field bounces to an area above the form.

Use relative positioning and fixed heights to prevent this
UI glitch.
