#692 Efabless Openlane PL_TIME_DRIVEN=1 mode is broken (Script: or_replace.tcl)

Time Driven Placement mode is broken in openlane setup (script: or_replace.tcl)
Run fails with below error message,
[INFO ODB-0134] Finished DEF file: input/6-pdn.def
[ERROR STA-0573] 'sky130_fd_sc_hd__inv_1' not found.
Error: 3-verilog2def.sdc, 153 STA-0573
Tools say's not able to find the sky130_fd_sc_hd__inv_1 in trimmed.lib
and inside trimmed.lib this Buffer is commented
/* removed
sky130_fd_sc_hd__inv_1 */
This issue is easily reproducible with just adding PL_TIME_DRIVEN=1 in any Efabless example project
Example:
exp12.tar.gz
Also replacing trimmed.lib with sky130_fd_sc_hd__tt_025C_1v80.lib also fails in next stage
