Is this a bug? (search and replace... replace fails)

Searches
--- SUCCESSFULLY return searches for the basic html syntax I tried (see details below)

--- REPLACEMENTS 100% totally fail (see details below)

I wanted to use "regex" but the replacements were failing
...so I switched back to "character match" to test if replacements worked
sadly replacements NEVER worked (see details below)

Basic HTML Removal Attempt #1 of 2
I tried using "Search Mode = character match" + "unchecking 'case sensitive'" + "Search field = 'comments'"

Searching for

Code:

; font-size: small

and replacing with
#nothing, blank, remote the text used in the search
does absolutely nothing.

Pretty simple I think, find this string of characters case insensitive then remote them.

Basic HTML Removal Attempt #2 of 2
Likewise I tried using "Search Mode = character match" + "unchecking 'case sensitive'" + "Search field = 'comments'"
Searching for

Code:

style="font-family: 'Times New Roman','Times','serif'; font-size: medium

and replacing with
#nothing, blank, remote the text used in the search
this does absolutely nothing.

These basic "Character match" SEARCHES succeed
... however the replacements fail

Is there anyway around this?
Is this a bug?

Exactly where are you trying to run the S&R?
