Parsing RENAME TABLE statment returns wrong tokens

[youthug]

Describe the bug
When parsing the RENAME TABLE sql statement by sqlparse.parse with this content:

rename table `db`.`test1` to test2, `db`.`test3` to test4

the result of ret[0].tokens:

[
00 = {Token} <Keyword 'rename' at 0x7F0B52882A00>
01 = {Token} <Whitespace ' ' at 0x7F0B52882A60>
02 = {Token} <Keyword 'table' at 0x7F0B52882AC0>
03 = {Token} <Whitespace ' ' at 0x7F0B52882B20>
04 = {Identifier} <Identifier '`db`.`...' at 0x7F0B47A030B0>  # value: '`db`.`test1`'
05 = {Token} <Whitespace ' ' at 0x7F0B52882CA0>
06 = {Token} <Keyword 'to' at 0x7F0B52882D00>
07 = {Token} <Whitespace ' ' at 0x7F0B52882D60>
08 = {IdentifierList} <IdentifierList 'test2,...' at 0x7F0B47A03890>  # value: 'test2, `db`.`test3`'
09 = {Token} <Whitespace ' ' at 0x7F0B52897040>
10 = {Token} <Keyword 'to' at 0x7F0B528970A0>
11 = {Token} <Whitespace ' ' at 0x7F0B52897100>
12 = {Identifier} <Identifier 'test4' at 0x7F0B47A03DD0>
]

Is this as expected? Should't the db`.`test3 be an Identifier too?

To Reproduce

import sqlparse

sqlparse.parse("rename table `db`.`test1` to test2, `db`.`test3` to test4")

Expected behavior
the db`.`test3 should be an Identifier too.
