Polar visualisation graph covers the number scale in Live Poll

[atbinix]

Hi,
We encounter an issue with the LivePoll graph where covers the number scale in Live Poll. Replication steps:
1-Click 'Turn editing on'
2-Click 'Add an activity or resource'
3-Select 'Live poll'
4-Provide a name and under live poll settings configure as follows (options do not matter, but ensure Result rendering is set as follows):

5-Select Save and display
6-Navigate to the participants page (and for example: login as a student)
7-Navigate to the recently created Live poll activity and select it
8-Note how the polar visualisation tool looks like (the number scale is perfectly visible):

9- Select Option A or Option B
Observation: The number scale on the visualisation tool is blocked by the generated segment

(v4.3.4)

Thanks.
