Base addresses not setting properly on PIE enabled binaries

radare2 2.2.0-git 16757 @ linux-x86-64 git.2.1.0-173-gf06a360
commit: f06a36097e7a310dbbc2ccd08f790119c31e100b build: 2017-12-19__18:44:21

While setting the base address with the -B switch in r2, it loads the base address fine.

└─▪ radare2 -B 0x40000000 funmail 
 -- The '?' command can be used to evaluate math expressions. Like this: '? (0x34+22)*4'
[0x40000540]> ij~{bin.pic}
true
[0x40000540]> 

But not when the e flag is being set even after reloading the binary.

└─▪ radare2 -e "bin.baddr=0x40000000" funmail 
 -- Setup dbg.fpregs to true to visualize the fpu registers in the debugger view.
[0x00000540]> ij~{bin.pic}
true
[0x00000540]> oo
[0x00000540]>

The same applies to setting bin.baddr from the console:

└─▪ radare2 funmail 
 -- Use scr.accel to browse the file faster!
[0x00000540]> e bin.baddr = 0x40000000
[0x00000540]> oo
[0x00000540]>

Additionally: after the binary is loaded with -B and debugged, the base address gets thrown off.

└─▪ radare2 -B 0x40000000 funmail 
 -- The more 'a' you add after 'aa' the more analysis steps are executed.
[0x40000540]> doo

The above is consistent with setting base address with bin.baddr also
