Installation bug - reboot didnt reboot but restart installation (existing in 5.95.x and 6.0 stable)

[odc2]

I have installed 5.95.x and 6.0 many times. While that i find many bugs on different x86_64 hardware (no hardware problem):
Here in this issue i report following bug:
When choosing the first option to install on the hdd and confirm that, i see then percentage of the installation. At some point it seems to have finished. But the screen is still at 8x%. When i press then left/right key button, the "OK" and "reboot" button suddenly appears. When i press then reboot, it restart the installation and didnt reboot.
I can reboot when pressing cancel on the (second)started installation and go then to reboot.
The installed system is starting fine then.
This bug didnt happen all the time.

Is something missing? I have written the version and the arch and its about the latest software.
