fix: Fix chart title truncating when Chrome is zoomed out

[kgabryje]

SUMMARY

When user zoomed out the browser (could repro only in Chrome, Safari and Firefox worked fine), titles of some charts would truncate. That's because for some reason (probably browser bug) the input container decreased it's width by 0.01px.
Also, confirmed that it's always just 0.01px, so this PR simply adds 1px to the input container as a failsafe.

TESTING INSTRUCTIONS

1. Open Explore, zoom out Chrome (with cmd -)
2. Verify that title is not truncated (unless it should be because there's actually too little space of course)
