Safari >100% zoom level misalignments

[monfera]

Describe the bug
When reviewing #651 I noticed that there can be overlap between the legend and sunburst in Safari when the browser zoom level (View / Zoom ...) is not set to 100%. Other things in eg. Cartesians are breaching boundaries too. Whether it happens under other conditions needs triaging, but on an initial look

• it doesn't happen with Crome or Firefox
• it's not specific to chart type or what is being rendered (legend, data ink etc.)
• protrusion seems to be Southbound and Eastbound

Screenshots

Here, upon reducing the width, the X projection shrinks to zero and then becomes negative (highest X is leftmost):

Version (please complete the following information):

• OS: recent OS X Catalina
• Browser: Safari Version 13.1 (15609.1.20.111.8)
• Elastic Charts: PR feat(tooltip): improve positioning with popperjs #651 checked out

tested in 63.0.0, seems solved (probably a safari issue)
