If you are developing full theme, you should edit css/core/global/framework/pagination.css and add

max-width: 100%

just below line 118, inside the selector

.ipsPager .ipsPager_next a, .ipsPager .ipsPager_prev a

 

Alternatively, if you're just modifying someone else's/the stock theme, add the following to custom.css:

.ipsPager .ipsPager_next a, .ipsPager .ipsPager_prev a {
	max-width: 100%;
}

and the change will be persistent across updates.
