Regression: Onscreen Keyboard Backspace, Enter and Capitalize do not work

[Esokrates]

Title pretty much says it all: I'm testing Ubuntu Hirsute (21.04), fully upgraded as of today (Gnome-shell 3.38.3) and the osk keys for Backspace, Enter and Capitalize as well as for collapsing the keyboard do not work. Pressing them just does nothing.

Fix proposed: https://salsa.debian.org/gnome-team/gjs/-/merge_requests/17

[Daniel van Vugt (vanvugt)]

The workaround is to reinstall the older version of gjs:

Thanks Daniel, great work as always! Confirmed that downgrading to gjs 1.67.2-1 and libgjs0g 1.67.2-1 solves the problem.
