Some EuiIcons missing viewBox attribute

[pickypg]

Some of the EuiIcon icons are missing the viewBox attribute, which causes them to not render properly [in Chrome at least].

All of these are set to size="l" :

If I manually modify the bottom two attributes to add viewBox="0 0 16 16":

Taking a look at the saved svg files, I noticed that they are either saved with or without viewBox attributes.

These are the files that do not have a viewBox:

$ find . -name "*.svg" -type f | xargs grep -L "viewBox"
