Magento admin showing multiple icons on buttons

Question

I see multiple icons on all admin buttons, please have a look at the screenshot below

And I see that Magento is spitting two extra span tags while it should wrap the button text in single span tag but for some reason, it wraps two more span tags. I have flushed Magento cache, cleared out contents of cache directory but all in vain. It's a weird behavior and I never encountered such issue before while working with Magento before.

Can anybody give me a clue?

Note: No JS error is there in the console. And, no relevant error found in Magento logs. Magento version is 1.9.3.9

The various icons appear to be a CSS issue, as each of these spans has the button.back span rule which apply the background. Actually, 3 span tags are not common, but here also have 3, but without the problem of the icons, because my CSS has these rules that I did not see in the image you uploaded:

button span span { background: none !important; padding: 0 !important; margin: 0 !important; display: inline !important; }
