Modern theme:
Open SM in MailNews, open a new compose window e.g. with ^m. Behind the From: is an input box with an arrow-down at the end. Clicking this arrow gives a choice of identities.

Default theme:
Like above. No arrow-down visible. Open the DOM Inspector. File->Inspect Chrome Document->Compose: (no subject). In the DOMI click on the 'Find a node...' icon and then in the compose window on the From:. In the left window of the DOMI now is a line with 'label' selected.

Open the menulist directly below label and click on xuldropmarker. In the compose window the end of the input box flashes red for a short time.

That indicates that the box containing the arrow-down exists despite being not visible.

That is not a new bug. I can reproduce it with older SMs.

I should add that the red flashing area at the end of the input box has the height of the input box and the width of only some pixel.
