translation inconsistency: no quote in attribute selector

[justnpT]

a = "//a[contains(@href,'attestation-upload')]" cssify(a)

output:

a[href*=attestation-upload]

expected condition:

in this case proper css selector, or the more accurate selector would be one with quoted value:

a[href*='attestation-upload']

I believe there should be an elegant way to make it happen
