Enable accessibility by default on Linux
Previously this was disabled unless the
QTWEBENGINE_ENABLE_LINUX_ACCESSIBILITY was set, as the debian packaging
was always enabling accessibility[1] even if a screen reader was not
enabled.
This is not the case anymore since 5 years ago[2] and now accessibility will
only be enabled if a screen reader is detected. Which is the correct
upstream behavior of at-spi2-core.
So now enable accessibility unless
QTWEBENGINE_ENABLE_LINUX_ACCESSIBILITY is set to 0
