Terminal hydrogens disappear when switching to Micro mode after opening a chain from a file in Macro mode

[Zhirnoff]

Description: When a chain is opened from a file in Macro mode with Flex display and the mode is switched to Micro, the terminal hydrogens on the chain disappear. However, if the chain is initially drawn in Micro mode and then switched to Macro mode and back, the terminal hydrogens remain intact.

Steps to Reproduce

1. Open Ketcher in Macro mode->Flex.
2. Import a chain from a file Chain.zip
3. Switch to Micro mode.
4. Observe the terminal hydrogens on the chain.

Actual behavior
For chains opened from a file in Macro mode, terminal hydrogens disappear when switching to Micro mode.
For chains drawn directly in Micro mode, terminal hydrogens remain intact when switching between modes.

Expected behavior
The terminal hydrogens should remain visible on the chain, regardless of whether the chain was opened from a file or drawn directly in Micro mode.
