FWIW, I can't seem to reproduce this on the Emacs master and emacs-26
branches (build info follows my signature).  Here's what I tried after
installing the fonts-tibetan-machine package on Debian:

0. emacs -Q
1. M-: (set-fontset-font nil 'tibetan "Tibetan Machine Uni") RET
2. M-: (insert "\u0f68\u0f7c\u0f7e\u0fc6\u0020\u0f40\u0fc6\u0020\u0f42\u0fc6") RET
3. C-x C-= = = = = = =   [Text scale +7]
