Split from B554 - Space after number for non ordinal letters with Auto correct on

Steps to reproduce

Test 3/4 test - Working fine with swipe

Test 3 test - Working fine with swipe

However with typing

Test 3/4test the word is glued to the number

Test 3test the word is glued to the number

What I expected

With Auto Correct on, results should be same as swipe/picked suggestion, for the typed words, except the ordinals like 1st, 2nd etc.

So with autocorrect, it should correct "3/4test" to "3/4 test" "3test" to "3 test".

Without autocorrect it should keep "3/4test" and "3test" as is.

What happened instead

Space is glued to the number even with auto correct.
